High gain, stability, and low input noise are the major concerns of a typical CSA circuit in order to achieve amplified susceptible input charge (current) for further processing. To design such a low-noise, stable, and low power dissipation solution, a CSA is required to be realized a complementary metal-oxide-semiconductor (CMOS) technology with a compact design. This research reports a low-noise highly stabile CSA design considerations for Silicon detectors applications, which has been designed and validated in TSMC 0.35um CMOS process. In a typical CSA design, the detector capacitance and the input transistor’s width are the most dominating parameters for achieving low noise performance. Therefore, the Equivalent Noise Charge (ENC) with respect to those parameters has been optimized, for a set of detector capacitance from 0.2pF – 2pF. However, the parallel noise of the feedback was removed by adopting a voltage-controlled NMOS resistor, which in turn helped to achieve high stability of the circuit. The simulation results provided a baseline gain of 9.92mV/fC and show that ENC was found to be 42.5e – with 3.72 e – /pF noise slope. The Corner frequency exhibited by the CSA is 1.023GHz and the output magnitude was controlled at -56.8dB; it dissipates 0.23mW from with a single voltage supply of 3.3V with an active die area of 0.0049 mm 2 .","PeriodicalId":56293,"journal":{"name":"Informacije Midem-Journal of Microelectronics Electronic Components and Materials","volume":"6 1","pages":"3-14"},"PeriodicalIF":1.2,"publicationDate":"2020-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74997699","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The accelerometers are generally divided into three categories of single axis, two axes, and three axes in terms of their ability to measure acceleration. In the suggested structure, acceleration measurements are carried out on all three axes simultaneously using a mass and spring system, which makes it possible to achieve a high sensitivity at a low occupancy level without losing other accelerator factors. By taking difference in this structure, it is shown that each axis acceleration has a very low impact on the measured acceleration of the other two axes. If any external factor changes the value of a single capacitor, the original output of the capacitor does not change for detecting acceleration. In other words, the acceleration of any of these three axes, due to its designing features, does not influence the other two axes and the system performance cannot be disrupted by external factors. The other important characteristics of the accelerometers are dynamic range, operating frequency and sensitivity. This study covers a dynamic range up to 1000g and an operating frequency up to 20 kHz. The accelerometer sensitivity is 4fF/g in the z axis direction while it is 9fF/g in the x and y axes directions. In this paper, the simulation of the structure is performed using Intellisuite software. Moreover, a multi-objective genetic optimization algorithm has been used to determine the dimensions of the constituents of the spring and the weight.","PeriodicalId":56293,"journal":{"name":"Informacije Midem-Journal of Microelectronics Electronic Components and Materials","volume":"5 1","pages":"55-66"},"PeriodicalIF":1.2,"publicationDate":"2020-04-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78609076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Digital Filters are used to filter the audio data stream and increase the reliability of speech signal. Therefore, it is imperative to design an area optimized and low power based reconfigurable FIR filter architectures. The reconfigurable architecture designed in this research is capable of achieving lower adaptation-delay and area-delay-power efficient implementation of a Delayed Least Mean Square (DLMS) adaptive filter with reversible logic gates. The Optimized Adaptive Reconfigurable Adaptive Reconfigurable (OAR) FIR filter architectures are proposed. The optimized architectures are implemented across the combinational blocks by reducing the pipeline delays, sampling period, energy consumption and area, to increase the Power-Delay Product (PDP) and Energy Per Sample (EPS).The noisy speech signals are used for verifying the efficiency of the proposed architectures. The efficiency of the architecture is verified by implementing the proposed scheme in signal corrupted by various real-time noises at different Signal to Noise Ratios (SNRs).","PeriodicalId":56293,"journal":{"name":"Informacije Midem-Journal of Microelectronics Electronic Components and Materials","volume":"20 1","pages":"241-254"},"PeriodicalIF":1.2,"publicationDate":"2020-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74057110","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multiple new methods have been developed in this field including Evolutionary Electronics. A lot of work has been done in this field but there is still a room for improvement since some of the solutions lack the flexibility (diversity of components, limited topology etc.) in circuit design or lack complex fitness functions that would enable the synthesis of more complex circuits. The research presented in this article aims to improve this by introducing Grammatical Evolution-based approach for circuit synthesis. Grammatical Evolution offers great flexibility since it is rule based – adding a new element is as simple as writing one additional line of initialization code. In addition, the use of a complex multi-criteria function allows us to create circuits that can be as complex as required thus further increasing the flexibility of the approach. To achieve this, we use a combination of Python and SPICE to create a series of netlists, evaluate them in the PyOpus environment, and select the best possible circuit for the task. We demonstrate the efficiency of our approach in three different case studies where we automatically generate oscillators and high/low-pass filters of second and third order.","PeriodicalId":56293,"journal":{"name":"Informacije Midem-Journal of Microelectronics Electronic Components and Materials","volume":"33 1","pages":"229-240"},"PeriodicalIF":1.2,"publicationDate":"2020-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74302883","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The former method is the most used. Its main disadvantage is puncturing of patient skin (finger pricking for example) which frequently causes pain and the risk of viruses and bacteria entering the body. The development of an effective and accurate noninvasive method for blood glucose monitoring has been recognized as a crucial goal for future studies of blood sugar and implementations of such methods into wearable devices. In this paper, we propose monitoring of blood glucose level employing skin impedance measurement. A measurement system featuring an Application-Specific Integrated Circuit (ASIC) is presented and analyzed. The fabricated ASIC in 350 nm CMOS technology with dimensions 1223 μm x 1388 μm, typically consumes 450 μA at 3.3 V supply voltage and operates in frequency region from 5 kHz to 16 MHz. The system exhibits a good linear response for loads up to a few kΩ, making it suitable for skin impedance measurements.","PeriodicalId":56293,"journal":{"name":"Informacije Midem-Journal of Microelectronics Electronic Components and Materials","volume":"61 1","pages":"255-260"},"PeriodicalIF":1.2,"publicationDate":"2020-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89280202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In order to minimize the material consumption and to accelerate the fabrication process, further thinning down of the absorber layer is important. Using a thin absorber layer results in a highly reduced photocurrent density and to compensate for it an effective light management needs to be introduced. Experimentally supported, advanced optical simulations in a PV module configuration, i.e. solar cell structure including the encapsulation and front glass are employed to design solutions to increase the short current density of devices with ultra-thin (500 nm) absorbers. In particular (i) highly reflective metal back reflector (BR), (ii) internal nano-textures and (iii) external textures by applying a light management (LM) foil are investigated by simulations. Experimental verification of simulation results is presented for the external texture case. In the scope of this contribution we show that any individual aforementioned approach is not sufficient to compensate for the short circuit current drop of the thin CIGS, but only a combination of highly reflective back contact and introduction of textures (internal or external) is able to compensate and also to exceed (by more than 5 % for internal texture) photocurrent density of a thick (1800 nm) CIGS absorber.","PeriodicalId":56293,"journal":{"name":"Informacije Midem-Journal of Microelectronics Electronic Components and Materials","volume":"81 1","pages":""},"PeriodicalIF":1.2,"publicationDate":"2019-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87078952","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
