Module Overview

This module focuses on how to create real electronic systems. It covers 'building block' circuits using biplolar transistors and FETs, and looks at the use and operation of op-amps. It also covers how to deliver timing in circuits, interfacing in mixed-signal electronic systems (using ADCs and DACs), and filters. It also looks at how to provide power to systems, and interface with sensors.
