Consider the MOSFET DA on Figure P2.1. Transistors Q, and Q, are n-channel MOSFETS with threshold voltages V, = Vt, = Vt = 2 V and transconductance parameters k1 =

k2 = k = 100 MA/v2-mA, Let IG,, ID,, and Is, be, respectively, the gate, drain, and source currents of Q1. Moreover, let IG,, ID,,and Is, be, respectively, the gate, drain, and source currents of Q2. 1. DC analysis: Find the operating points (Qpoint) of both Q5 and Q6. Differential Mode: Express and compute the Differential Mode gain Adm:а. b. Common Mode: Express and compute the Common Mode gain Acm- c. Compute the Common Mode Rejection Ration (CMRR) in dB.
