Analog Electronics unit (ENG234)

Introduction

The unit introduces the fundamental concepts of modern electronics based on semiconductor devices. On completion of this unit you will be able to design amplifier circuits with feedback. Beginning with the basic atomic structure of doped silicon substrates, diode construction, operations and characteristic curves are introduced, leading to DC and AC analysis. This is expanded to quiescent point setting and AC small-signal analysis of common transistor types (BJTs, JFETs, MOSFETs). Capacitive decoupling, voltage gain, input and output impedance, effective bandwidth, cascaded systems (both with and without the loading effect) will be explored, along with circuit component interaction on low frequency responses and parasitic effects on high frequency responses (Miller capacitance). The construction of common operational amplifiers will be reviewed and used to design active filters, with non-ideal equivalents used to describe its limitations. The benefits of an instrumentation amplifier over an operational amplifier will be investigated. Finally, the effect of shunt and series feedback on stability, gain and effective bandwidth will be analysed. These are fundamental circuit types required for control and communications systems, and advanced embedded systems, which are studied later in the degree.
