Clamper Circuit
The capacitor will maintain the voltage placed on it, and will be successful as long as the period of the waveform is much less than the RC time constant τ. It will then produce a voltage equal to the maximum value of the input waveform, V max. This voltage is added to the whole waveform, thereby boosting the voltage level of the entire AC signal.
