A circuit includes a complementary current mode logic driver circuit and a dual feedback current mode logic bias circuit. The complementary current mode logic driver circuit provides a first output voltage and a second output voltage. The dual feedback current mode logic bias circuit includes a first feedback circuit and a second feedback circuit. The first feedback circuit provides a first bias voltage for the complementary current mode logic driver circuit in response to the first output voltage. The second feedback circuit provides a second bias voltage in response to the second output voltage.
