Abstract
A receiver includes a Gilbert cell mixer comprising an input transconductance stage. The input transconductance stage includes first and second transistors receiving an input signal and providing a first gain characteristic that is substantially non-linear over an operating frequency range of the receiver. Third and fourth transistors receive the input signal and provide a second gain characteristic that is substantially non-linear over the operating range of the receiver. A combined gain characteristic of the input transconductance stage is based on the first and second gain characteristics and is substantially linear over the operating frequency range of the receiver.
