The Design of an Operational Amplifier
More details are given in the report. Hence, if you are interested in knowing more about the project, you may choose to skip to the report directly.
The aim of this assignment is to design and simulate a single-ended differential amplifier which is used as an op-amp to simulate other circuits such as amplifiers, filters, oscillators, and negative differential resistance.
The differential amplifier utilises a voltage-biased MOSFET as the common current source at the common source. It also uses other efficient techniques such as a cascode MOSFET arrangement and a cascode current mirror on the drain side.
