Unformatted text preview: Homework 3 Due February 14 P3.1) In the circuit shown, (a) Find the fraction of the ac source cycle during which the diode conducts? (b) Find the peak charging current? (c) Find the maximum reverse bias across the diode. Assume that the diode is ideal. P3.2) Assuming ideal diodes, find the value of the currents, I1 and I3, in the two circuits below P3.3) At what temperature is the thermal voltage equal to 25mV? Use the values for the Boltzmann coefficient and electronic charge given in lecture to compute T. P3.4) A particular n=1 diode D1A is found to exhibit a forward current of 3 mA at an applied diode junction voltage of 0.7V and at an operating temperature where Vt=25mV. (a) Determine the saturation current, Is? (b) Another diode D1B is manufactured using the same fabrication process as D1A. The only difference is the cross-sectional area of D1B is 10x larger. Find the reverse leakage current of diode D1B at a diode voltage of -1V. P3.5) Sedra and Smith 4.23 P3.6) Sedra and Smith 4.41 ...
