This course provides a comprehensive introduction to analogue electronics, circuit analysis and power electronics. The aim of the module is to deliver a basic understanding of the principles of analogue electronics, circuit analysis and power electronics, the means by which the response of systems can be analysed and modeled in both the time and frequency domain, and to understand and model the small signal response of amplifier circuits.

By the end of the module students will:

• Understand, and be able to apply to a range of practical situations, the basic scientific principles underlying electrical circuit theory;
• Calculate the voltages, currents and powers in DC, AC and transient circuits.
• Understand the concept of linearity and time-invariance in electrical circuits.
• Apply appropriate quantitative mathematical, scientific and engineering tools (including complex algebra and differential equations) to the analysis of circuit-related problems, such as calculating power factor, roll-off, cut-off frequency, resonant frequency, damping factor, Q-factor, and circuit time constant.
• Design circuits for practical applications, such as a resonant RLC circuit for bandpass filtering in a wireless receiver.
• Understand the concept of power in ac and dc circuits and be able to analyse the power efficiency of real transformer and other circuits including concepts of 3-phase power and its advantages. Analyse different 3-phase configurations using electrical circuit theory.
• Understand the physical principles, operating parameters and small signal analysis of BJT and MOSFET. Understand the limitations and advantages/disadvantages of different devices.
• Design amplifier circuits to have desired gain and output voltage range characteristics. Understand and be able to apply trade-offs between parameters in the design process.
• Understand the concepts of rectification and regulation and be able to design simple power supply and regulation circuitry.
• Understand the design issues in building multistage amplifiers with desired gain and bandwidth - choice of building blocks, input and output characteristics, driving loads.
