BUFFER AMPLIFIER CIRCUIT FOR ENHANCING SLEW RATE OUTPUT SIGNAL THEREOF AND DECICES HAVING SAME

摘要

A buffer amplifier circuit includes a buffer amplifier which includes a first differential amplifier having a first active load and a second differential amplifier having a second active load; and a feedback circuit which feeds back the output signal of the output terminal of the buffer amplifier to either the first active load or the second active load by using differential switch signals and the input signal of the buffer amplifier, and improves the slew rate of the output signal.
