The photocurrent generated by 1D carrier transport equations is instead of ideal double exponential current model within bias-dependent single-event compact model to analyze the behavior of bulk CMOS being striking. Firstly, the approach using a 1D photocurrent equation to emulate the current curve verses the LET is explained in section II. Then a stand bipolar SPICE model with injection photocurrent is modeled by bipolar affects analysis. This work proposes an improved current injected model.","PeriodicalId":150727,"journal":{"name":"The 2012 International Workshop on Microwave and Millimeter Wave Circuits and System Technology","volume":"17 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122310851","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}

GSACEA combines the genetic algorithm and the simulated annealing algorithm into the solution for coverage-enhancing in directional Doppler sensor networks. By simulations, comparing our proposed algorithm with other classic directional sensor networks coverage-enhancing algorithm, GSACEA can achieve higher area coverage rate with lesser iterative computing times.","PeriodicalId":150727,"journal":{"name":"The 2012 International Workshop on Microwave and Millimeter Wave Circuits and System Technology","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-04-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129716625","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 method makes envelops of echo pulses automatic alignment in the fast-slow time domain. At the receiver, combining the Fractional Fourier transmit (FrFT), two index phases caused by the acceleration can be compensated, so the Doppler shift can be compensated simultaneously.
