This work presents a novel technique for controlling the displacement of the switch membrane. The technique shows exceptional capabilities of achieving soft landing of the membrane on contact pads at pull-in voltage, and significant improvement of pull-out transient. The control technique presented in this work is physical based and generic in nature, thus making it adaptable and scalable to any switch. Comparison between switch behavior with and without control shows 80% improvement in impact dynamics and approximately 70% improvement in overshoot and settling time during pull-out.","PeriodicalId":117453,"journal":{"name":"2013 IEEE 20th International Conference on Electronics, Circuits, and Systems (ICECS)","volume":"488 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115297247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although a fractal image has high correlation between its pixels, the proposed technique succeeds in almost eliminating this correlation and the output stream passes the NIST statistical test suite. The post-processing on the fractals is based only on a confusion process and uses a nonlinear network with a delay block to randomize the output stream. Many statistical measures and the NIST suite have been used to evaluate the processed fractals and the results are promising. As an example to validate the PRKG, the output stream is used in a simple image encryption system. The encrypted image is tested by calculating pixel correlations, differential attack measures, entropy and it also passes the NIST test suite.","PeriodicalId":117453,"journal":{"name":"2013 IEEE 20th International Conference on Electronics, Circuits, and Systems (ICECS)","volume":"58 6","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120809109","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The resonator tank, consisting of a fixed-value inductor and a variable capacitor, was implemented in the MetalMUMPs process and was targeted for a VCO intended for telemetry applications. A geometrically optimized 1.25 nH horseshoe inductor was designed and results show that it exhibits a Q-factor of 63 at 7.3 GHz and a self-resonating frequency of 17.6 GHz. In addition, an improved π-inductor model is proposed for design and simulation purposes. The variable capacitor was designed in a parallel-plate topology, using four serpentine springs. The capacitance can be varied from 0.183 pF to 0.245 pF with an actuation voltage in the range of 0 V-to-11.7 V. A Q-factor of 62 at 1.1 GHz and a self-resonating frequency above 10 GHz were achieved.

The differential amplifier, major part of total circuit, is responsible by amplifying the input signal as well to provide a DC level for it. Thus, adjusting it for excursion in range between 0 V and a reference voltage value defined. The input signal being measured comes from external environment, like a data acquisition system. The buffer circuit makes a copy of the output voltage from the differential amplifier at its own low impedance output, providing analog signal for an analog to digital converter.

Our investigation on this shows that most researchers are mainly using simulation to test healthcare systems. However, lack of simulation frameworks that support security, makes this method an improper technique to verify security in WBSN. Thus, a formal verification technique is proposed in this work for the verification of security aspects in healthcare systems. We adopt a firstorder theorem proving method (Event-B) to model WBSN and verify security requirements such as privacy at different levels of abstraction.","PeriodicalId":117453,"journal":{"name":"2013 IEEE 20th International Conference on Electronics, Circuits, and Systems (ICECS)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115096161","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The principle of proportional match design in the resistor switch network, its structural characteristics and the resistor network for calibration are elaborated. In order to cancel the variation of switch network resistance value caused by process, temperature and voltage, a new calibration circuit has been proposed. Finally this paper proposed an automatic calibration algorithm based on fuse trim, which can significantly improve the efficiency of trimming and lower the cost of DAC chip. Simulation results show that the linear error, differential error and full scale error of the converter all meet the requirements of 12-bit resolution.

In many of these applications, compact models of microbatteries are needed both at the microsystems design stage and at the real-time power management stage. These compact models are typically derived from physics-based discretized formulations. We have developed a simplified partial-differential equation (PDE) model for an allsolid state Li metal microbattery. The simplified PDE model was solved using a finite-difference scheme implemented in Matlab. The simplified model is within 2% of the full non-linear model yet runs 6 times faster.","PeriodicalId":117453,"journal":{"name":"2013 IEEE 20th International Conference on Electronics, Circuits, and Systems (ICECS)","volume":"93 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116717861","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, new improved synaptic plasticity rules, such as Triplet-based Spike Timing Dependent Plasticity (TSTDP), are capable of replicating many biological experiments outcomes including the results of the experiments carried out in the visual cortex. This paper proposes a programmable analog neuromorphic circuit, which is capable of reproducing pairing frequency experiments in the visual cortex. The circuit utilizes transistors working in their subthreshold region of operation. In addition, it implements a minimal model TSTDP learning rule, which needs a low number of transistors compared to its PSTDP circuit counterparts. These features result in low-power compact circuits that are suitable for large-scale VLSI implementations of Spiking Neural Networks (SNNs) with improved synaptic plasticity and learning capabilities.","PeriodicalId":117453,"journal":{"name":"2013 IEEE 20th International Conference on Electronics, Circuits, and Systems (ICECS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128751286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore the reference voltage has to be highly insensitive and independent on substrate variations. The proposed design shows 1.4% accuracy over process variations and mismatch. The line sensitivity was measured to be 4mV/V. Measurements have proven that the isolation of the output of the reference voltage from the substrate potential is working properly.
