Type of module:

Summary module description:
This module provides a foundation in the theory that supports the understanding of DC and AC (frequency dependent) circuits, and circuits that contain logic elements and Operational Amplifiers (Op-Amps). This module also introduces the analysis and design of such circuits.

Aims:
This aim of this module is to provide students with the background knowledge, theory, skills and tools to enable them to analyse and design simple electronic circuits that consist of the most common components and elements that include voltage and current sources, resistors, capacitors, inductors, logic gates and operational amplifiers.

Assessable learning outcomes:

By the end of the module the students should be able to do the following when given sufficient information:

•             Recognise, and describe and apply the theory underpinning, voltage and current sources, resistors, capacitors, inductors, logic gates and operational amplifiers.

•             Analyse circuits consisting of voltage and current sources, resistors, capacitors, inductors, logic gates and operational amplifiers, and determine the currents, voltages and power outputs of such circuits.

•             For AC (frequency dependent) circuits, be able to describe and calculate the behaviour of such circuits in the frequency domain, specifically how the gain of such circuits varies with frequency and also to be able to identify common filter types such as low-pass and high-pass.

•             Perform analysis of logic circuits and form, manipulate and simplify logical expressions.

•             Analyse circuits that include Op-Amps, including the application of feedback.

Outline content:

Logic: (5 lectures) gates, levels, Boolean algebra, multiplexers, demultiplexers, encoders and decoders.

Circuits: (20 lectures) Fundamental concepts, power sources and electronic components. Passive and active circuits. Network analysis, Kirchhoff's laws, Thevenin and Norton's theorems. Representation of electrical signals, vector diagrams, complex representations for ac signals. Free and forced response of circuits containing L, C and R. System response, Q factor and resonance. Frequency response, first and second-order filters. Power in ac circuits, rms values, power factor.

Op-amps (10 lectures) Op-amps are useful electronic components which in practise are connected in feedback loops. This strand covers ideal op-amps, effect of negative feedback, non-inverting and inverting voltage amplifiers, op-amp's limitations, special purpose networks, instrumentation amplifiers, active filters, non-linear feedback, voltage comparators, positive feedback and its applications. Level shifters, voltage and current references. Sample and hold, analog multiplexers, Schmitt triggers, and oscillators.

Semiconductor devices (5 lectures): Atomic structure and electrons. Insulators, conductors and semiconductors. Intrinsic and extrinsic semiconductors. Majority and minority carriers. p-n junction diodes. Zener diodes. Light emitting diodes. Bipolar junction Transistors (the Common Emitter and Common Collector amplifiers, the Differential Amplifier, Operational Amplifiers and configurations), Field Effect Transistors.

Penalties for late submission:
The Module Convener will apply the following penalties for work submitted late:

• where the piece of work is submitted after the original deadline (or any formally agreed extension to the deadline): 10% of the total marks available for that piece of work will be deducted from the mark for each working day[1] (or part thereof) following the deadline up to a total of five working days;
• where the piece of work is submitted more than five working days after the original deadline (or any formally agreed extension to the deadline): a mark of zero will be recorded.

• The University policy statement on penalties for late submission can be found at: http://www.reading.ac.uk/web/FILES/qualitysupport/penaltiesforlatesubmission.pdf
You are strongly advised to ensure that coursework is submitted by the relevant deadline. You should note that it is advisable to submit work in an unfinished state rather than to fail to submit any work.
