Positive clamper with positive reference voltage

Clamper circuit is mostly used for clamp the input signal.The main affecting part of the circuit is capacitor and due to its charging function,it charge in first positive half cycle of input signal and then it reflects input signal to output as same.If we want to clamp the output signal as our requirement then we can add dc supply in the circuit and get the output as shown in the figure.in this we added the supply as the diode remains at positive terminal of supply.practically we can get the clamped output signal clamps to the breakdown voltage of the diode (i.e. 0.5 V).we can change the parameter as per our requirement.
