Abstract
A variable gain amplifier (VGA) useful in a receiver that recovers transmitted digital signals. A first amplifier in the VGA has a first gain, an input coupled to an input of the VGA, and an output coupled to a load. A second amplifier in the VGA has a second gain, an input coupled to the input of the VGA, and an output coupled to the load. In a first mode of operation, the first gain is substantially zero and the second gain ranges between a maximum gain and a fraction of the maximum gain. In a second mode of operation the first gain is substantially the maximum gain and the second gain ranges between the maximum gain and the fraction of the maximum gain, and an algebraic sum of the first gain and second gain is no greater than the maximum gain to reduce non-linear distortion at low VGA gain.
