Further, assume that the DC current of M1 and M2 is 1 mA each and that of M3 and M4 is 0.5 mA each. Assume all transistors are in operating in saturation region and the aspect ratio of transistors is as follows: (W/L)1 = 125, (W/L)2 = 250, (W/L)3 = 40, and (W/L)4 = 80. a) Find transconductance (gm) of all the transistors and the drain-source resistance (ro) of the PMOS transistors, that is, ro2 and ro4. [10 marks] b) Find the voltage gains Vout1/Vin and Vout /Vin. .
