EL ENG 42 Study Guide - Final Guide: Diode, Linear Circuit, Current Source
Document Summary
Frustrated at how inaccurate all our linear diode models have been, john decides to cook up another one. The zener diode below has a linear on characteristic and a breakdown voltage vb like any other, but it is modeled as a capacitor cd when it is reverse-biased, or off. id (a) 1 vd (v) (a) (3 points) let"s rst analyze the diode in its forward-bias (on) mode. Label the directions of vd and id. id. 1 v vd (b) (3 points) john attaches this diode to a circuit as shown below. On the plot below, draw in the load line imme- diately after the current source turns on, i. e. , t = 0+. Be sure to label slopes and intercepts; your plot need not be to scale. id (a) 3 (c) (3 points) suppose the capacitance of the diode is cd = 1 f (10 6 f).
