(a) Design a single-stage inverting amplifier with a gain of 46 dB using an operational amplifier. The input resistance should be as low as possible while achieving the op amp output drive capability mentioned here. The amplifier must be able to produce the signal vo = (10sin1000t) V at its output when an external load resistance RL ≥ 5k Ω is connected to the output of the amplifier. You have an operational amplifier available whose output is guaranteed to deliver ±10 V into a 4-kΩ load resistance. Otherwise, the amplifier is ideal. (b) If the amplifier input signal is vi = V sin1000t, what is the largest acceptable value for the input signal amplitude V? (c) What is the input resistance of your amplifier?
