Six inverters are shown below. Assume that Kn = 2Kp and that λn = λp and that the DC bias current through each inverter is equal. Qualitatively select, without using extensive calculations, which inverter(s) has/have (1) the largest AC small signal voltage gain (2) the lowest AC small signal voltage gain (3) the highest AC output resistance (4) the lowest AC output resistance. Assume all devices are in saturation.
