    ESD structure of pin DVSS and pin AVSS

    Re: About ESD Thanks! We don't add ESD between pin DVSS and pin AVSS. ESD structure of Pin VCC to Pin AVSS is same,the difference of added voltage between Pin VCC to Pin AVSS is same. I want to ask why VCC,AVSS TO DVSS (-) is NO pass, but AVSS,DVSS TO VCC(+) is pass?

    ESD structure of pin DVSS and pin AVSS

    ESD model:HBM , Pass Volt:2500V Pin DVSS and Pin AVSS pass :VCC, DVSS TO AVSS (+) VCC, AVSS TO DVSS (+) AVSS,DVSS TO VCC(+) Pin DVSS and Pin AVSS no pass: VCC, DVSS TO AVSS (-)...

    class AB APA crossover distortion

    thanks Do you have anyway to remove the crossover distortion without increasing bias current.

    class AB APA crossover distortion

    I am designing class AB CMOS audio power amplifier,now I meet a problem. There is a crossover distortion at OUTPUT. MOS bias current is 1.2 mA,load RES=3 ohm if load res >16 ohm,corossover distortion disapper. I don't know how remove crossover distortion. please help! thanks

    NMOS of CMFB in linear region

    I meet a full differential amplifier.there is a NMOS of CMFB in linear region always. the other simulation's result is right, I don't know that if it ok.who would help me? thanks
