For the circuit in the figure, assuming that the op-amp is ideal in all respects: 1. Derive an expression for the gain of the circuit, vv, as a function of frequency. 2. Sketch the magnitude of the gain in dB versus w using a Bode plot. Use the following values for the passive components: C= 10 pF, R1 = 10 k2 and R2 = 100 kn. Label the axes carefully so that the slope of any lines may be clearly seen. R1 www R2 www C

The figure below plots the frequency response of a multi-pole amplifier. A feedback system employing this amplifier with K = 1 will be: Bode Diagram Magnitude (dB) Phase (deg) 0 -20 40 -60 -80 -100 -90 -135 -180 -225 10-1 10° Frequency (rad/s) Select one: O a. stable because WGX wpx 10¹ 10²

For the circuit in the figure, assuming that the op-amp is ideal in all respects: 1. Derive an expression for the gain of the circuit, v /v, as a function of frequency. 0 2. Sketch the magnitude of the gain in dB versus w using a Bode plot. Use the following values for the passive components: C= 40 pF, R1 = 2.5 KQ and R2 = 25 kn.
