Abstract
A self-bias signal generating circuit includes a differential amplifier circuit including a current source transistor. The differential amplifier circuit is configured to amplify at least a pair of differential input signals to generate at least a pair of differential output signals, and the differential amplifier circuit is configured to generate an output common-mode signal based on the at least a pair of differential output signals. The self-bias signal generating circuit includes a feedback loop circuit configured to adjust a voltage level of the output common-mode signal to generate a self-bias signal, and the feedback loop circuit is configured to provide the self-bias signal to the differential amplifier circuit. The self-bias signal is applied to a gate terminal of the current source transistor.
