High-speed CMOS buffer circuit with programmable quadratic transfer function

摘要

An asymmetry correction circuit for correcting an asymmetry signal includes a first transconductance circuit for transforming the asymmetry signal to a bias current in a first current path, a second transconductance circuit to form the bias current in a second current path, and a feed-forward circuit for transforming the asymmetry signal to a positive difference current and a negative difference current.
