Objective: Design an amplifier with improved Frequency Response
Assignment Details:
One of the key applications of MOSFET is in amplifier design. Using the circuit shown in Fig.1, MOSFET can
amplify a small, time varying input signal. The two conflicting requirements in amplifier design are its high gain
and large bandwidth. In this assignment, the main goal is to design an amplifier with a specified gain and
identify a solution to improve its bandwidth.

Assignment Deliverables and Constraints:
Following are the assignment deliverables and constraints
1. Use Fig. 1 to design a single stage amplifier with a gain and low cut off frequency as follows
195
Gain (Gy) 4+ 100
Low cut off frequency (fi) = 200 +1

H=
2. Find higher cutoff frequency (fx) using simulation OR hardware experiment.
3. Conduct a thorough literature review of how frequency response of a MOSFET amplifier can be
improved. List down their advantages and disadvantages.
4. Based on the above literature review, propose a new design to improve bandwidth of the amplifier in
Fig. 1. Provide a detailed analysis of how your proposed design works. Specify the bandwidth
improvement of your proposed design.
5. Explain the tradeoffs in the design of both amplifiers.
