2.23 Consider the same amplifier as in Exercise 2.22—that is, an inverting amplifier with a nominal gain of 1000 constructed from an op amp with an input offset voltage of 3 mV and with output saturation levels of ±10 V—except here let the amplifier be capacitively coupled as in Fig. 2.32(a). (a) What is the dc offset voltage at the output, and what (approximately) is the peak sine-wave signal that can be applied at the input without output clipping? Is there a need for offset trimming? (b) If R1 = 1 kΩ and R2 = 1 MΩ, find the value of the coupling capacitor C1 that will ensure that the gain will be greater than 57 dB down to 1 kHz. (a) 3 mV, 10 mV, no need for offset trimming; (b) 0.16 µF
