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.
