Question

(15 marks) Here is an amplifier operating from VDD-3 V. Rsig-5 kΩ RL = 1 kQ, CL = 100 ff, CGS-20 fF, CGD-4 fF. Assume the dc component of R. si a) Find the dc drain current Id, the dc component of Vo and the MOSFETs b) Draw an ac small-signal equivalent circuit that includes all relevant c) By writing the necessary nodal equations, find the transfer function d) Using the values for the capacitors, resistors etc, determine the poles e) Comment on what would happen to the Q factor of the poles if Rı were transconductance, gm. capacitors. (T(s) Vo/Vsig). Please leave this in symbolic form and zeros of the circuit. replaced by an ideal current source adjusted to give the same drain current as calculated in a)

    Problem 3: Design Problem On Figure P3a, you have a Common Source (CS) n-channel MOSFET amplifier. Notice the absence of a source resistor Rsig and load resistor R. If we know how the present amplifier (the one on Figure P3a) behaves without Rsig and RL, we can infer its behaviors if Rsig and R were to be added. design the amplifier circuit on Figure P3a, i.e., you have to find appropriate values for RGj You are to RG,, RD, and...
