Abstract
A system and method for implementing an amplifier capable of limiting or clamping an amplifier output signal is described. A clamp buffer and an input buffer cooperate to bias an output circuit according to the relative level of a clamp signal and an input signal. In a normal mode, in which the input signal has a first relationship with the clamp signal, the output circuit provides an output signal based on the input signal. In a clamping mode, in which the input signal has a second relationship with the clamp signal, the output circuit provides an output signal based on the clamp signal, which can be substantially fixed. The clamp signal can be set by the user to establish a desired clamping range.
