Abstract
A buffer amplifier circuit includes a buffer amplifier including a first differential amplifier having a first active load and a second differential amplifier having a second active load and a feedback circuit configured to feed an output signal of an output terminal of the buffer amplifier back to one of the first and second active loads using differential switch signals and an input signal of the buffer amplifier to enhance a slew rate of the output signal.
