ABSTRACT:
A linearized bipolar differential input stage that contains two high gain current mirrors coupled in series with the input voltage signal through the input transistors to allow the output differential current to greatly exceed the DC output current in a Class AB fashion. The extended output current range over and above the DC current significantly lowers the percentage of effects for both DC offset and noise in the output signal path. Non-linearity cancellation is also optimized for the lowest level of input distortion through adjusting transistor area ratios.
