    PMOS for ESD protection????

    Hello, If it is PMOS Source ,drain ,bulk : VCC ,Substrate : Ground . ESD can be positive strike as well as negative Strike . If it is positive strike ,well to substrate junction will be broke down ,ESD charge will be bypassed to ground. If it is negative strike ,well to substrate...

    High speed amplifier - choice of topology

    Re: High speed amplifier ...here you can use current buffer compensation for compensating Amp Without loosing Amp Speed significantly .Here assumption is Amp is two stage[First is gain stage & second is class-AB] &Amp has to drive huge load cap and compensation cap is placed between first stage...

    High speed amplifier - choice of topology

    Re: High speed amplifier Hello , The available best solution for designing High Slew Rate /Ultra low power bias current Amp is using Class-AB output stage .The available Class-AB output Topologies are Floating Current Source biased Output Stage & Source Follower type Output stage .each have...

    What's the difference between feedback and compensation?

    Hello , Generally compensation of Amp will be done for good Phase margin .This good phase margine gives better settiling time when Amp used in feedback. definetly compensation also a feedback ..but this feedback has to apply only on Amps who are having better phase margin . Ex : In Two stage...

    Oversampling method for ADC

    hello , At ADC oversampling fundamental assumptions are : Quantization noise samples are statistically independent [uncorrelated ] and signal samples are correlated . So, quantization noise samples will be added under square root where as signal samples will be added linearly .which is SNR...
