Gain Stabilization Mechanism Through Dynamic Common Mode Feedback and Gain Booster in Folded Cascode Track and Hold (T/H) Circuit

A low power Folded Cascode Track and Hold Amplifier (THA) circuit has been designed and analysed. The design of THA is to facilitate the development of ADC with specification 12-bit resolution, 125kSPS, and 1MHz. THA is used to sample and hold the input signal before it is being digitized. Ideally,...
