ECE 3042 Homework Assignment No. 2 Spring 2010 Homework for Experiment No. 2 Due Week of February 1 1. Design a non-inverting amplifier that uses a single ideal op-amp as the active element and has a dc gain of 52 ,aninfinite input impedance, and an output impedance of zero. Use resistors that are larger than 100 and smaller than 1M . 2. Design a non-inverting amplifer using ideal op-amps as the active element that uses three stages of amplification. The specifications for the gain, input and output impedances are identical to those of Problem 1.Make the gain of the first two stages 2 and the third stage 13 . Perform an AC analysis of each of the circuits designed with National Instruments SPICE if the op-amp is a TL071. For the National Instruments SPICE use the virtual three terminal model for the op-amp; set the unity

Unformatted text preview: gain frequency to 3MHz for the TL071. Use the frequency range 1kHz to 10MHz with 100 points per decade. Plot both axes on a log scale. Use the cursors to determine the low frequency (dc) voltage gain and the 3 dB frequency. Compare the simulation results to the theoretical expectations. Plot the response of both circuits on the same sheet of graph paper so that the performance can be compared. For the theoretical value use the result that would be predicted by the dominant pole model of the op-amp. 3. If three stage of gain are used, what should be the gain of each stage to maximize the 3 dB bandwidth? The amplifier is non inverting, the overall dc gain is 52 , the input impedance infinity and the output impedance zero....
