Question

Assume in all problems a) Nonideal diodes are 1mA diodes (Vd=0. 7V for ld=1ma) with a slope of 60mV/decade of current, b) Non ideal op-amps have GB=1MHz and A_gIDC=100,000V/V, R_j=100kohm, R_0=50ohm, c) Zener diodes with Vzk=5. 2V, lzk=1mA, r_2=10ohm, d)NMOS and PMOS transistors have following parameters gain factor beta=k_0W/L=2mA/V^2, Threshold voltage V_t=1V, lambda=0. 0V^-1 e) Bipolar transistors have a common emitter gain current beta=100, alpha=0. 99 and Early Voltage V_A=100VB Problem 1. What is the voltage Vd across the terminals of a nonideal diode with a current ld=100mA? a) 0. 7V b) 0. 76V c) 0. 82V d) 0V e) 0. 64V f) none of the previous Problem 2. What is the load resistance in a full wave rectifier with f=50Hz, C=1650uF, Vp=165V, Vr=1V. Assume ideal diodes a) 20kohm b) 10kohm c) 1kohm d) 100ohm e) 1Mohm f) None of the previous

Explanation / Answer

PD remains the same . So it is 0.7v
