Repeat Problem 9.21 except use the aspect ratios, supply voltages, and bias current given in Fig. 6.58 instead of the values in Fig. 9.60. Also, assume that X_d= 0.1 µm for all transistors operating in the active region, and use Table 2.4 for other parameters.

Data from Prob. 9.21:

For the CMOS operational amplifier shown in Fig. 9.60, calculate the open-loop voltage gain, unity gain bandwidth, and slew rate. Assume the parameters of Table 2.1 with X_d = 1 µm. Assume that the gate of M₉ is connected to the positive power supply and that the W/L of M₉ has been chosen to cancel the right half-plane zero. Compare your results with a SPICE simulation.
