Current mode logic circuit and method

摘要

A circuit includes a bias generating circuit, an operational amplifier, and a current mode logic circuit. The operational amplifier has a first input terminal, a second input terminal, and an output terminal. The bias generating circuit is configured to provide a first bias voltage to the first terminal. The second terminal is configured to receive a second bias voltage. The second terminal and the output terminal are configured to form a negative feedback loop. The output terminal is coupled with the current mode logic circuit.
