How does over-voltage of the diode usually occur?
how does the relationship of voltage vs. current when the diode is forward biased differ from that of the resistors
1. a) State the diode equation and explain the significance of each term. b) Sketch the current - voltage characteristics for a typical silicon diode over the 4 voltage range -2 V to +2 V. Explain how the characteristics would change if the diode was fabricated using germanium. Give an equivalent circuit representation of the device in each case. c) In a silicon diode a current of 200 HA flows when a forward bias voltage of 0.5 V4 is applied...

Problem 3: (20 points) A zener-diode voltage regulator circuit is shown belkw zener diode has breakdown voltage Vz 8.0V and the zener resistance is nsumed to be 0 ohms. The power supply voltage Vps can vary between 10V and 14V and the lod resistance Ri can vary between 100 ohms and 1 kohm, 圧 1. Find a value of R such that the zener diode remains properly biased over the range of variation of Vps and RI (hint: the minimum...
Give a physical interpretation to the phenomenon that the (small) reverse current of a pn-junction diode does not increase when the reverse-bias voltage increases (before reaching the breakdown voltage).
