Abstract
A gain-enhanced high-speed single-stage class-AB low-power op amp is presented. Positive feedback scheme is used to increase the voltage gain. On the other hand by utilizing current driven bulk technique the output voltage swing is improved. Employing two cross-coupled flipped-voltage-follower blocks, class-AB behavior is achieved to make the op amp compatible for high-speed low-power applications
