Consider the CMOS current–gain op–amp in Figure 13.18. Assume the bias current is IQ = 200/µA and assume transistor parameters , Assume the basic W/L ratio of the tran­sistors is 40 and let B = 3. (a) Determine the small–signal voltage gain, (b) If the effective capacitance at the output node is Cl + Cp = 2 pF, determine the dominant pole frequency and the gain–bandwidth product.
