Slew rate control boost circuits and methods
Abstract:
The present disclosure amplifier circuits and methods having boosted slew rates. In one embodiment, an amplifier circuit comprises an output stage comprising a first output transistor, the first output transistor comprising a gate, a source, and a drain, wherein the gate receives a signal to be amplified. A bias circuit biases the gate of the first output transistor. A damping circuit is coupled the gate of the first output transistor and is configured to produce a high impedance at low frequencies and a low impedance at high frequencies. The damping circuit includes a current limit circuit to limit current to the gate of the first output transistor when a voltage on the gate of the first output transistor decreases in response to the signal.
