Patent ID: 8416969

Claim:
A linear amplifier circuit comprises: differential amplification circuitry comprising: an input stage having first and second differential inputs, and an output stage, having respective first and second amplifier components with first and second differential outputs; wherein the first amplifier component of the output stage comprises: a first power transistor operably coupled to the first differential output and driven by a first differential output of the input stage, and a third power transistor operably coupled to the first differential output of the amplifier circuit and driven at a control electrode by a voltage at a second output of the input stage, wherein the second amplifier component comprises: a second power transistor operably coupled to the second differential output and driven by a second output of the input stage, and a fourth power transistor operably coupled to the second differential output and driven at a control electrode by a voltage at the first output of the input stage; wherein each of the first and second power transistors of the first and second amplifier components is driven in a current mirror arrangement by the respective first and second output of the input stage.
