Question

Description Simulate the following circuit using Multisim using the constant voltage drop model. For the diode, use the Diode_Virtual component in Multisim. Find the Q points for each of the three diodes by running a DC Operating Point analysis. Answer questions 1 to 6 using the results of your simulation. QUESTION 1 1D1 in mA. QUESTION 2 VD1 in V. QUESTION 3 1D2 in mA QUESTION 4 VD2 in V. QUESTION 5 1D3 in mA. QUESTION 6 VD3 in V. the input in the following figure is expressed as Vx = Vo cos wt, choose the correct current flowing through the circuit as a function of time. Assume VD,on = 800mV for the constant-voltage diode model. Assume the axis origin is (0,0) for both current and voltage.

Explanation / Answer

Ans 1.

I1 is current through D1 from -ve to +ve terminal , I2 through D2 from +ve to -ve, (I1-I2) through R1 , I3 through D3 from +ve to -ve.

applying KVL in loop V1-R3-D1-D2-R2-V3

-20 -10k*I1 +0.7-0.7 -10k*I2 - 10k* I3 + 10 =0

-10 - 10k*I1 -10k* I2 - 10k* I3=0 ---------------------1

KVL in loop D3-R2-V3

-0.7
