Exercise 5 The operational amplifier in the following circuit is ideal. Lets Ra C = 0.1F, R = 2.5kQ, R = 10k, and C2 1F. = = 10, R1 = 50, The power supply voltage for each op amp is 6. The signal voltage (vg) for the cascaded integrating amplifiers jumps from 0 to 250 mV at t = 0. No energy is stored in the feedback capacitors at the instant the signal is applied.
