    Consider the amplifier shown below. M2 is PMOS transistor and M1 is NMOS. VDD is dc power supply voltage. Calculate small-signal gain of the amplifier. All the transistors have channel length modulation, i.e., do not ignore ro. Further, assume transistors M1 and M2 have same transconductance of gm and same channel resistance of ro. Calculate small signal gain of the amplifier.
