ECE 2204 Electronics Fall 2009 Quiz #5 October 16 (Friday) Weight: 10 points Name (PRINT): \ce Cy ID# Consider the circuit below, where R; = 3 KQ, Rz = 3 KQ, and Rp = 10 KQ, and Vpp = 6 V. 1. Show the Q-point using load analysis for Ip versus Vps curves of the NMOS given below. Vi 32 2. An input voltage is applied to the circuit, which causes Ves to increase by 1 V from the Q-point. Show the new operating point denoted as “R’ in the graph. 3. Let the voltage Vos at Q-point as Vpsq and the valtage Vps at R-paint as Vosr. Similarly, Vesa and Vesr are the Ves voltage at Q-point and R=point, respectively. Then, the voltage gain A, is defined as follows. Find the voltage gain. Show your work. A= Vosr7Vpsg — Vesr-Vasq ey) 2 Nex
