A peak hold circuit includes an input node configured to receive an input waveform, a peak hold component coupled to the input node and configured to sample and hold a peak value of the input waveform at a peak value node, a reset node configured to receive a reset signal, a reset circuit coupled to the peak hold component and the reset node, the reset circuit configured to reset the peak hold value, and a voltage clamp coupled to the input node, the reset circuit, and the reset node, the voltage clamp configured to clamp the input node in response to the reset signal.
