8.71 Consider the cascode amplifier of Fig. 8.33 with the dc component at the input VI = 0.6 V, VG2 = 0.9 V, VG3 = 0.4 V, VG 4 = 0.7 V, and VDD = 1.3 V. If all devices are matched, that is, kn1 = kn2 = kp3 = kp4, and have equal  Vt  of 0.4 V, what is the overdrive voltage at which the four transistors are operating? What is the allowable voltage range at the output?
