The bias current in the CMOS current-gain op-amp in Figure 13.18 is IQ = 120µA. The transistor parameters are 0.015V-1and λp = 0.04 V–1. The transistor width-to-length ratios are 20 except for M5 and M6. Let B = 3. (a) Determine the small-signal differential voltage gain, (b) Find the output resistance of the circuit, (c) If the total capacitance at the output terminal is 5 pF, determine the dominant-pole frequency and the unity-gain bandwidth.
