Refer to the MOSFET circuit above. Given Rsi = 50 Ω, R1 = 325.00 kΩ, R2 = 180.00 kΩ, and RD = 0.75 kΩ. If the transistor has an Early voltage of VA = 10^4 V, k = 0.7 mA/V^2, ID = 2.10 mA, and VTN = 1.50 V, what is the value of the small signal output resistance of the transistor?

For the small-signal amplifier in the figure, the transistors have the model parameters: ̢ = 100 and VBE = 0.6V. Capacitor CE is AC short-circuited at the operating frequency. Calculate: a) the DC operating point b) draw the AC circuit c) the voltage gain d) the input and output resistance

For the given circuit, find the small-signal voltage gain Av = vo / vi. Draw the small-signal equivalent circuit. Assume MOSFET is in saturation mode, and the BJT is in forward active mode. CC1, CC2, CC2 are sufficiently large. For JFET: IDSS = 16 mA, VP = -8 V and VA = ∞, (use ID = IDSS(1 - VGS/VP)^2, gm = 2IDSS/|VP|(1 - VGS/VP). For BJT: β = 85, VBE = 0.7 V, VA = ∞, VT = 25 mV. RG = 0.5 MΩ RS = RE = 4 kΩ RC = RL = 4 kΩ
