In the circuit below R1 2k ohm RL 7k ohm D2 has a forward

In the circuit below, R1 = 2k ohm, RL = 7k ohm, D2 has a forward voltage of 0.7V and a Breakdown voltage of 200V V2 = 1.2 cos(2 pi(1000t)) V V1 = 9V Find the voltage at Va. Find the bias condition for the diode (V_D, l_D) due to the DC source. Use the diode SSM to find the time varying voltage across the diode due to V2. Putting together b and c, what is v_0(t)

Solution

a) Va= square root of(9²+(1.2/1.414) ²)= 9V
