Abstract
An amplifier may include an output stage including first and second output transistors, and a biasing stage for generating first and second biasing voltages at control terminals of the first and second output transistors, respectively, based upon a supply voltage and an input signal of the amplifier. The amplifier may also include a clamping stage having first and second clamping transistors for clamping outputs of the first and second output transistors to upper and lower clamping voltages, respectively. Additionally, the amplifier may also advantageously include a saturation detector connected to the clamping stage for providing a saturation signal for at least one of (a) the output of the first output transistor being clamped to the upper clamping voltage, and (b) the output of the second output transistor being clamped to the lower clamping voltage.
