Abstract
A complementary cascode push-pull amplifier circuit includes a bias generator, a complementary bias generator, a cascode input stage (416, 417), a cascode output stage (410, 411), a complementary cascode input stage (456,457), and a complementary cascode output stage (450,451). The bias generator is responsive to a first input signal (420) and generates a bias control voltage. The complementary bias generator is responsive to a second input (421) and generates a complementary bias control voltage. The cascode output stage (410, 411) and the complementary cascode output stage (450,451) each have an output coupled to a common output terminal (510) for generating a portion of an output current signal in response to the respective input signals (420, 421) and in response to the bias control voltage and the complementary bias control voltage being generated.
