Digital subtraction limits the final resolution of the difference. Analog subtraction yields limitations in gain, range and sensitivity, respectively and may suffer from imperfections of the analog subtraction circuitry (e.g. matching, non-linearity, etc.). In this article, an approach is explained and demonstrated to maximize signal range, sensitivity and final resolution for the difference of two or more (sensor) input signals by utilizing integrating amplifiers with differential outputs. The correlated double-sampling concept is extended therefore. Signal properties and system constraints are explained. The applicability is demonstrated by a 0.6μm-CMOS implementation example for the subtraction of two photo-current input signals within a single transimpedance amplification stage.","PeriodicalId":271676,"journal":{"name":"2011 IEEE 9th International New Circuits and systems conference","volume":"140 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116500087","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 metrics studied to characterize the PUFs are Randomness, Uniqueness and Steadiness. They take advantage of the measured physical values of elementary component making up the PUF. The delay distributions provide the interest to quantify the PUF at the physical level rather than carrying out a lot of experiments to get the PUF IDs at logical level. An Arbiter PUF composed of identical chains has been considered as a test chip to evaluate the method with the proposed metrics. Experiments have been carried out on CYCLONE II FPGA and the corresponding results shows the intra-device performance of the studied PUF.","PeriodicalId":271676,"journal":{"name":"2011 IEEE 9th International New Circuits and systems conference","volume":"114 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122008663","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}

To demonstrate the potential of these technologies, this paper presents some examples of MMICs and modules developed for use in next generation remote sensing and communication systems.

Firstly, it deals with the requirements of a general purpose opamp and introduces the need of the frequency compensation in the current circuits. Then, the rules to integrate multipath in an opamp are developed and the transfer function is presented and compared to the one of the nested miller compensation. Next, an implementation of the multipath nested miller compensation is described. Finally, simulation result which proves the efficiency of this compensation is given. The multipath compensation improves the classical compensation structure as it does not cutoff the initial unity gain frequency by four but only by two.","PeriodicalId":271676,"journal":{"name":"2011 IEEE 9th International New Circuits and systems conference","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134409028","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 problem of latch, which is not encounted in conventional LC oscillator, is essential in our case. With a careful design in bias this problem is solved. This oscillator has the advantage of inherent opposite polarity appeared on the terminals of SAW resonator, which leads to fast growing amplitude during transition. As compared to the well known Colpitts oscillator, the transition period is significantly shrinked. For completeness three kinds of oscillator with single ended, balanced Colpitts, and cross coupled one are compared in terms of figure of merit (FOM) under the same magnitude across the resonator.

The proposed ADC is based on a novel capacitive DAC switching scheme which employs unit capacitors for voltage sampling and charge redistribution.

The proposed 8-bit SAR-ADC is designed in Global foundries 65nm CMOS process. SPICE simulation results show that the average switching energy can be reduced by more than 60% compared with published design. The simulated power consumption of the capacitive DAC is about 110 nW at 1.0 V power supply and 100KS/s.
