Multiple output amplifiers and comparators

Abstract

An amplifier/comparator includes a multitude of output stages all sharing the same input stage. One or more of the output stages are amplification stages and have compensated output signals. A number of other output stages are not compensated and provide comparison signals. Each uncompensated output stage is adapted to switch to a first state if it detects a first input signal as being greater than a second signal, and further to switch to a second state if it detects the first input signal as being smaller than the second signal. By varying the channel-width (W) to channel-length (L) ratio (W/L) of the transistors disposed in the output stages, the trip points of the comparators and/or the electrical characteristics of the amplifiers are selectively varied.
