Module 4 — Electronic Fundamentals

4.1.3 — Integrated Circuits

Practice questions test what you know. This note teaches what you don’t.

Question banks train recall. The questions that decide a pass are the borderline ones, where two answers look right — and those are won by understanding. That is what this note is written for.

Inside this note

Locked

Integrated circuits (ICs) combine a few dozen to billions of transistors, resistors, diodes, and capacitors on a single semiconductor chip. They are the foundation of all modern avionics, flight computers, communication systems, and instrumentation. This section covers both digital (logic) and analogue (linear) ICs, with a focus on operational amplifiers and their applications.
