ABSTRACT:
Methods and structures are provided to enhance the linearity of amplifiers such as those which include a complementary common-collector amplifier stage. The methods and structures configure this stage so that each transistor of the stage drives an output port through a linearizing resistance. The methods and structures then control a bias current through the stage to substantially be the thermal voltage VTdivided by twice the linearizing resistance.
