ECE 3042 Homework Assignment No. 2 Fall 2010 Homework for Experiment No. 2 Due Week of September 13 1 .ShownbelowinFigs .1and2aretwononinvertingopampamplifiers. The components have been se- lected so that the dc gain of each is 100 .The first, shown in Fig. 1, is realized as the cascade combination of two inverting op amp amplifiers. The second uses one op amp in the noninverting amplfier configuration. For the circuit in Fig. 1 use 1 =1k and =10k For the circuit in Fig. 2 use 1 =1k and =99k Fig. 1 Fig. 2 Use either Cadence or National Instruments SPICE to plot the small signal gain versus frequency as the frequency varies from 1kHz to 10MHz

Unformatted text preview: amp which assumes that the unity gain frequency is 1MHz Plot the frequency response for the two amplifiers on the same sheet of graph paper. 2 . Shown in Fig. 3 is a T Feedback op amp amplifier. Design a T Feedback op amp amplifier with a dc gain of − 100 The input impedance is specified to be 10k Ω . Use either Cadence or National Instruments SPICE to plot the gain versus frequency as the frequency varies from 1kHz to 10MHz Assume that the op amp in a 741 and use the dominant pole model for the op amp for which the unity gain frequency is 1MHz Determine the 3 dB bandwidth and compare it to the theoretical value.
