VI. Draw the small signal model, including source-drain resistance, and find the small-signal gain (in V/V) for this current-mirror loaded CS transistor amplifier. For all transistors: W/L = 50 Vt = |0.5 V| VA = 20 V IREF = 100 µA µnCox = 100 µA/V^2 µpCox = 50 µA/V^2 iD = 1/2µnCoxW/L(VOV )^2 gm = µnCoxW/L VOV = 2ID/Vov = √2µnCoxW/LID
