简介：互补金属氧化物半导体(互补金属氧化物半导体)电压控制了戒指振荡器因为极端高频率(UHF)收音机频率鉴定(RFID)读者被认识到并且描绘。在宪章0.35m互补金属氧化物半导体过程制作了，全部的薄片尺寸是0.47

简介：<正>一般来说,需使用有源器件的75-100GHzW波段的毫米波被认为是Ⅲ-Ⅴ族化合物半导体技术的天地。但随着fT/fmax频率超过150GHz,更新的SiGe工艺可竞

简介：Thevoltagecontrolledoscillator-based(VCO-based)continuous-timedelta-sigma(CTDS)analogtodigitalconverter(ADC)suffersfromnonlinearityandmismatchinitsfeedbacknetwork.Anewfeedbacknetworkconsistingofaphaseshifterisproposed.Thephaseshifterreplacesthedigitaltoanalogconverter(DAC)intheproposedarchitecture.Feasibilityoftheproposedideaisdiscussedanditshigherperformanceisillustratedthroughabehavioralsimulationapproach(CppSim).Wehavealsodevelopedthephaseshifterasavariableall-passfilterintheClanguage.ThenonlinearityandmismatchofthesystemcausedbyDACismitigated,resultinginhighersignaltonoiseratio(SNR)andsignaltonoiseanddistortionratio(SNDR),respectively.
