Abstract:
Embodiments of the invention are generally directed to improving the slew rate of an amplifier as the amplifier charges or discharges a capacitive load. In one embodiment, the amplifier is coupled to a slew-enhancing circuit which uses a control signal from the amplifier to aid the amplifier when charging or discharging the load. For example, the control signal may be an internal voltage used by the amplifier to control circuit elements within the amplifier. By routing the control signal to the slew-enhancing circuit, the control signal biases the circuit elements within the slew-enhancing circuit to source a boost current when charging the capacitive load or sink the boost current when discharging the capacitive load.
