The circuit seen in Fig XXXXXXXXXXis an another example of a circuit that sums the currents from NMOS and PMOS diff-amps (so the input common-mode range can extend from beyond the power supply rails)....

The circuit seen in Fig. 22.40 is an another example of a circuit that sums the currents from NMOS and PMOS diff-amps (so the input common-mode range can extend from beyond the power supply rails). Describe and simulate the operation of this circuit using the short-channel parameters in Table 9.2 and the bias circuit from Fig. 20.47.
