Abstract

A high linearity transconductance stage is arranged with a loss cancellation method to remove the nonlinearity of a typical transconductance circuit. The loss cancellation method uses a series of transistors and resistors to supply a controlled feedback current to cancel the result of the change (.DELTA.) in voltage across the input of the transistor used to provide the transconductance for the transconductance stage of a circuit, such as an amplifier, a mixer or other active circuit.
