The NMOS transistors Q and Q2 in Fig. 4 having gm = 1 mA/V are operated in saturation. Ignore the channel-length modulation and body effects for these devices. Assume VDD = 5 V and Vss = -5 V. (a) (10 points) Find the open-circuit voltage gain, v1/v₁, and output resistance Rol. (b)(10 points) Find the input resistance R₁2 and the voltage gain, vo/v2. (c) (10 points) Now, if the voltage node v₁1 is connected to the node v₁2, find the overall voltage gain, vo/vi.
