Abstract:
A circuit is disclosed to enhance slew rate of an amplifier. An amplifier includes an output, a first input, and a second input in a differential pair configuration. A slew rate enhancer includes a first slew rate enhancer and a second slew rate enhancer. The first slew direction enhancer is configured to detect a first slew rate condition in a first direction responsive to the first input and the second input and provide additional current for a first side of the differential pair of the amplifier during the first slew rate condition. The second slew direction enhancer is configured to detect a second slew rate condition in a second direction responsive to the first input and the second input and provide additional current for a second side of the differential pair of the amplifier during the second slew rate condition.
