Question

V DD Problem #4: Design an amplifier based on the circuit to the left. Design for a gain of 10V/V, an input resistance of at least 1M92, and a bias current of 0.1mA. Choose the maximum Rs value that allows the maximum input signal to be amplified and remain linear and in saturation (i.e. use the definition of linear amplification for a FET and saturation). Assume VTN = 1.0V, kn’W/L = 0.5mA/V2, Vpp = 10V, R=1k2, and R3=470k 2. R2 SRD C2 RI ci wa + sº Ra BS + c3
