This module builds on the concepts in analog electronics that students have encountered in their first year, including fundamentals of low and high frequency small signal analysis of BJT and MOSFET circuits. Fundamental concepts such as filters, feedback, bode plots, power amplifiers and oscillators will be explored. The aim of this module is to give students a good introduction to the analysis of standard circuit configurations, such as single-stage amplifiers and feedback circuits, and the design of advanced circuits, such as operational amplifiers and oscillators.

By the end of the module students should be able to:

• Understand basic single-transistor amplifier configurations, i.e., CE, CB and emitter follower for BJT, and CS, CG and source follower for MOSFET.
• Use small-signal equivalent circuits in analysing circuit performance
• Analyse the low-frequency response of discrete-circuit amplifiers and estimate the corner frequency.
• Analyse the high-frequency response of discrete and integrated amplifiers using Miller theorem and open-circuit time constant methods
• Sketch the magnitude and phase response of an amplifier in a Bode plot
• Understand filter basics
• Understand general structure of negative feedback amplifiers and the basic principle that underlies their operation
• Use positive or negative feedbacks in realizing analog circuit blocks
• Design differential and multi-stage amplifiers down to transistor level
• Understand the different classes of power amplifier and be able to analyse them (class A, B, and AB)
• Learn how positive feedback is applied to make oscillators and be able to analyse different types of oscillator circuits
• Understand the operating principles of tuned amplifiers
• Use SPICE to simulate circuit behaviour
