Question

a- 2.21 pF. b- 4.25 pF - 0.75 pF. d 0.168 pF 8) Consider a p-n junction at T 300 K in which s 10-14 A and n 1. if vo is diode current io is (Hint: you used the equation to find to in your last lab)l 0.7 V, then the a- 4.93 mA b -10-* A c 2 mA. d- 9.25 mA 9) A Zener r Diode has a Vr-0.7 V and a Vz of 9V. When the diode is forward biased,it would drop ia voltage of a- 0.7V. b- 9v. c 8.3V d- 9.7V. R1 Vout 1kO 01 8 Vpk 1kHz 10) The circuit is: a- Half wave rectifier. b- Full wave rectifier. c- Voltage Clamper. d- Voltage Limiter. 11) The output voltage Is limited in the: a- Positive half cycle of the input. b- The negative half cycle of the input. c- The whole Vin. d- None of the above

Explanation / Answer

Id = Is*((e^(Vd/nVt))-1) = (10^-14)((e^(0.7/0.026))-1) = 4.926 mA = 4.93mA

9) in forward bias voltage in zener will be 0.7V

10) it is voltage limiter circuit

11) output voltage will be limited in positive half cycle of the input because diode will get on when positive terminal get 4 v or above and output will get saturated at 4.7 v and in negative cycle dioded will be off so all wave will pass to the output
