Abstract :
The modified method of the increase of the response speed of flash ADCs with the differential input which renders possible to reduce the effect of the parasitic capacitances of active and passive components of the analog sections and also to optimize their gain flatness is reviewed. The additional emitter follower and balancing capacitor are fed into each analog section to extend the bandwidth of ADC up to 50 GH.
