From the project

Four-stage MOSFET amplifier design in KiCad, with transistor models, project report, and design guidelines.

Four stages. A 3.3 V supply. A study in gain, bandwidth, power, and output headroom.

An analog electronics project for ELE404: Electronics I at Toronto Metropolitan University, built in KiCad 9 with the supplied NMOS models. Three common-source stages provide voltage gain; a common-drain stage buffers the output.
