Abstract
The self correcting scheme to match pull up and pull down devices includes: a first comparator for comparing a common mode signal to a high reference limit; a second comparator for comparing the common mode signal to a low reference limit; a first flip flop having an input coupled to an output of the first comparator; a second flip flop having an input coupled to an output of the second comparator; a counter having inputs coupled to the first and second flip flops; and a delay device controlled by an output of the counter, wherein the delay device provides a pull down control signal that is delayed relative to a pull up control signal.
