Abstract
A two-stage fully-differential amplifier achieves a relatively high unity gain frequency yet has the current consumption by a second stage limited by a bias transistor that supplies current to an internal power supply rail. The internal power supply rail supplies power to two pairs of transistors for the second stage.
