Abstract :
A topology for a differential CMOS buffer amplifier is introduced. When compared to a popular differential amplifier cascaded with a source follower buffer, the new topology offers a better-controlled voltage gain at the same power dissipation. The new topology can have increased settling time, but the factors affecting its time domain response are discussed.
