The CMOS current gain op-amp in Figure 13.18 is to be redesigned to provide a differential voltage gain of 400. The transistor parameters are  0.015V–1and λm = 0.015 V-1. The bias current is to be IQ = 80 µA. Let B = 2.5. (a) Design the basic amplifier to provide the specified voltage gain, (b) Design a current source to provide the necessary bias current.

(c)  Determine the unity-gain bandwidth if the capacitance at the output terminal is 3 pF.
