2.25 Consider a Miller integrator with a time constant of 1 ms and an input resistance of 10 kΩ. Let the op amp have VOS = 2 mV and output saturation voltages of ±12 V. (a) Assuming that when the power supply is turned on the capacitor voltage is zero, how long does it take for the amplifier to saturate? (b) Select the largest possible value for a feedback resistor RF so that at least ±10 V of output signal swing remains available. What is the corner frequency of the resulting STC network?
(a) 6 s; (b) 10 MΩ, 0.16 Hz
