Abstract:
Devices, systems and methods for clamping output voltages of op-amps while minimizing post-clamping recovery delays are described. A circuit, which controls transitions between two operating modes, may include a first comparator for comparing an output voltage with a clamping voltage and outputting a first mode signal, a second comparator for comparing an input voltage with a reference voltage and outputting a second mode signal. A first logic component may receive the mode signals, perform a logical operation, and output a logic signal. A duplex output, based on a value of the logic signal, may output a track signal and an inversely corresponding hold signal, such track and hold signals being used by an op-amp circuit to configure adjusting blocks used to control transients during mode transitions.
