Abstract
A post-mixer amplifier device which receives and processes signals for use in a software-defined radio integrated circuit is provided. The post-mixer amplifier device includes but is not limited to a voltage amplifier having first and second inputs and a first output, a positive signal output connected with the first output of the voltage amplifier, and a positive signal input connected with a first bipolar junction transistor along a first pathway. The first bipolar junction transistor includes but is not limited to a first collector connected with a the first input of the voltage amplifier and a first emitter connected with an second output of the push-pull unity gain follower and forming a first current feedback pathway. The first bipolar junction transistor is driven with a passive resistive load.
