Abstract
An amplifier for amplifying a differential input signal. The amplifier comprises a parallel configuration of a first and a second transistor differential amplifier, each responsive to a different DC bias current, wherein a gain of the amplifier is based on a sum of the transconductance of each of the first and the second differential amplifiers.
