Abstract:
In an embodiment, a differential amplifier includes: an input stage; an output stage coupled to the input stage, the output stage having first and second output terminals; and a feedback circuit coupled to the output stage, where the feedback circuit is configured to dynamically adjust a bias current of the output stage based on voltages of the first and second output terminals.
