EEE335/EEE348 (analogue): Coursework.

Your task is to design an amplifier, simulate it in LTSPICE, and assess its performance. You may choose any of the amplifiers featured in the course material, or beyond, *apart from the two-stage differential amplifier covered at the end of the course*. Your design should be actively loaded so that it is suitable   for implementation as an IC.

The transistors in your amplifier should be taken from the following table:

You are free to choose the power supply voltage from the range 1.33-6V and the channel width, W, for the transistors in your design (the channel length, L, is as indicated in the ‘technology node’ row of the table).

--- You will need to submit a report, 10 pages maximum, to include the following ---

•    A description of your amplifier: what are its key properties, what applications might it be used for?       [5]

•    A small signal model of your amplifier.                                                      [5]

•    An assessment of the small signal performance of your amplifier, including your estimates (arrived at by hand calculations) of maximum signal levels, maximum signal swing, voltage headroom requirements, mid-band gain, output resistance and upper cutoff frequency.     [5]

•    Plots and results from appropriate simulations together with an assessment of the accuracy of your hand calculations.           [5]

•    A discussion on how realistic your model is: what is not included and how might these additional features effect the performance of your amplifier?       [8]

•    Improvement(s) to your design, e.g. better current mirror(s).                        [15]

The deadline for submission is Sunday, February 5, 2023 at 23:59 pm.

REMEMBER: This is a graded assessment, where a score of 50% equates to a 1st. You will need to demonstrate real understanding of the material to access the higher marks.
