The MOSFET-based common-source amplifier can be combined with a BJT emitter-follower output stage to construct a circuit that provides voltage gain while taking advantage of the high input impedance of the MOSFET and low output impedance of the emitter follower. For the following, T = 27 C, RD = 5 kΩ, RE = 2 kΩ, VIN, DC = 0.9 V, VDD = 5 V, and CL = 1 uF Use the Analog Devices MAT-02 npn transistor (VA = 150 V, β = 500, IS = 0.6 pA) for your analysis and simulations. Use the Level 1 NMOS SPICE model provided with the assignment (μ = 350, Cox = 384 nF/m2 Vth = 0.7 V, λ = 0.01 V−1, W = 100 μm, L = 1 μm). Analysis a) Estimate the DC operating point of the circuit ( ID0, IC0, V1, DC, and VOUT, DC ) assuming λ = 0 for M1 and VBE = 0.6 V, IB = 0 for Q2.
