Consider the common source amplifier with resistor degeneration shown below. Let VT 0.6V, I₁ 50μA, k = 1.5mA/V²,
VA = 75V, Rs = 2.5k and R₁ = 50k. Additionally, let Cgd = 100pF with negligible Cgs and Cds. Assume that the amplifier is
biased such that it operates in the saturation region with Voy = 0.25V. To simplify things, recall the two-port network equivalent
circuit of an NMOS transistor with resistor degeneration from previous discussions and quizzes. Express your answers up to FOUR
decimal places.
