Abstract
A buffer circuit having both high gain and high slew rate is implemented using a high gain-low slew rate amplifier and a switch network. The buffer circuit's operation is divided into three periods. During the first period, the output of the amplifier is isolated from the load to allow the amplifier's output voltage to more quickly reaches its final voltage level. During the second period, the switch network couples the amplifier output lead to the load input lead where the amplifier drives the voltage at the load's input lead to a voltage substantially equal to the voltage of the input signal. During the third period, the switch network isolates the amplifier from the load and couples the load's input lead to a source of ground potential to quickly slew the load's input lead to ground potential.
