A diode can be used as a voltage regulator, since the voltage drop across it is relatively constant in forward bias operation. For the circuit below, if the voltage v; is a DC voltage of 4.6 V with a 0.5 V (peak to peak) ripple on it and the resistor is 2.0 k, what is the ripple (peak to peak) at the output v, in mV, using a small signal model for the diodes. Assume the diode is at a temperature where VT-25 mV and the diode has n=1, and has a forward voltage drop of Vpo-0.7 V. Vion Vo
