Abstract
A dynamic amplifier with a bypass design. An input pair of transistors receives a pair of differential inputs Vip and Vin and further provides first, second and third terminals. A load circuit provides a pair of differential outputs Vop and Von with the load circuit connected at a common mode terminal. In an amplification phase, a driver for amplification is coupled to the first terminal and the load circuit is coupled to the second and third terminals. A bypassing circuit is specifically provided. The bypassing circuit is coupled to the second and third terminals during a bypass period within the amplification phase.
