Answer as quickly as possible. I'll give upvote. Thank you. The circuit shown is a common source amplifier with a current mirror bias. It is given that the NMOS (M1) parameters are μoCox = 3mA/V2, VTH,n = 0.5V and λ = 0.02 and the PMOS (M2 and M3) parameters are μoCox = 1mA/V2 and VTH,p = −0.6V . The PMOS transistor M3 does not have channel length modulation while PMOS transistor M2 has λ = 0.02. It is also given that the dimensions of M2 and M3 have equal widths of 5µm and lengths of L2 = 3µm and L3 = 1.5µm, respectively. M1 has length of L1 = 1µm and width of W1 = 2µm. Find the gm and ro of transistor M1.
If the inputs A and B are 0 and 1 respectively, Q5 will:
(i) cause the LED to turn off
(ii) a collector-emitter voltage approximately 0 V
(iii) at cut-off
(iv) a negative base-collector voltage
