Unformatted text preview: Randall P Robert 9771 EE 3221-SEC 5 Lab #4-Exp#15 Design of Test Circuits & Ring Oscillator Partner: Jason M 10/20/04 Objective To design circuits which compare the response of enhancement-mode FET’s with that of bipolar transistors and to study the performance of CMOS circuits, and to apply ring oscillators to evaluate the high-frequency response of CMOS inverters. Part 1 The procedure was followed in the lab manual to prepare a triangular wave signal from 0 to 5V at a frequency of 1 to 1.2 kHz that will be used throughout the experiment. Part 2 Resistor values are: R 1 = 1MΩ R 2 = 1kΩ R 3 = 1kΩ R 4 = 1kΩ For simplicity the scope readings are attached at the end of this report. Can you detect any current drawn by the FET? ٠ Due to the infinite input impedance no current was detected. What Vt do you measure on the scope? ٠ 2V At what input voltage does C start to decrease in voltage?...
