Summary  This course introduces students to the important analogue circuits of active filters, sine wave oscillators, relaxation oscillators, switched capacitor circuits and phaselocked loops. The aim is to present and instil the principles of circuit operation and the essential circuit analysis and design techniques to enable students to understand and design the simpler variants of the above circuits and to be capable of extending their understanding to more complex variants.

Learning Outcomes
On completion of this course, the student will be able to:
 Demonstrate and work with a full knowledge and understanding of the principles, terminology and conventions of analogue circuits, especially active filter circuits, oscillator circuits, switched capacitor circuits and PhaseLocked Loops (PLL).
 Use a wide range of prior knowledge (including algebraic manipulation, calculus, nodal analysis, Laplace Transforms, operational amplifier circuits, feedback, bode plots, pole/zero analysis) to analyse and design circuits in the categories given in 1 above, and to apply them to different filter sections, sine wave oscillators, relaxation oscillators, multiplier circuits, phase detector circuits, and subcircuits that may be used in such circuits.
 Analyse, specify, conceptualise and synthesise systems and applications that require the use of the circuits in 1 and 2 above, including some that were previously unknown.
 Understand, and be able to analyse and mitigate, the effect of component tolerances on the performance of the circuits in 1 and 2, including the ability to select appropriate component values and types to achieve a specification.

Reading List
Recommended :
"Integrated Electronics", J. Millman & C.C. Halkias (McGrawHill, 1972, ISBN 007Y854939)
Background:
"Active Filter Design", A. Waters, MacMillan, 1991, ISBN 0333488628. Sadly this is out of print and there is only a single copy in the Robertson library. It is short and very good on the filters material.
"Modern Communication Circuits", J Smith, McGrawHill, 0070587302
"Electronic Communication Techniques", P H Young, Merrill, 0024312010
"PhaseLock Basics", W F Egan, Wiley, 0471242616. This is very good on PLLs only.
