Unformatted text preview: Solution Part (a) This is an enhancement-mode device. Part (b) Make a plot of Then extend the plot to vs. with is the saturation region, for example at , and estimate (see below). 21 = 15 V. 55:041 Electronic Circuits. The University of Iowa. Fall 2011. Problem 19 For the circuit below, determine . (5 points) Solution The gate current is zero, so Further ( Thus ( ( Solving using trial-and-error gives 2.57 V. 22 ( ( 55:041 Electronic Circuits. The University of Iowa. Fall 2011. Problem 20 Determine the output resistance for the circuit shown. (5 points) Solution To determine set the independent source ( to 0, and add a test voltage and determine the test current that flows. This is shown in (a) below. Note that , so that the voltagecontrolled current source is off, and the equivalent circuit is shown in (b). (a) (b) 23...
