Document Summary
E10. 1 solving equation 10. 1 for the saturation current and substituting values, we have. E10. 2 the approximate form of the shockley equation is exp( / Taking the ratio of currents for two different voltages, we have i. Solving for the difference in the voltages, we have: v. Thus to double the diode current we must increase the voltage by. 0. 026ln(10) 59. 87 mv and to increase the current by an order of. The load-line plots are shown on the next page. From the plots we find the following operating points: (a) E10. 4 following the methods of example 10. 4 in the book, we determine that: At the intersections of the load lines with the diode characteristic we find (a) v. E10. 5 writing a kvl equation for the loop consisting of the source, the resistor, and the load, we obtain: The corresponding load lines for the three specified values of il are shown: v= .
