Analogue Electronics (Circuits) 4 (U04027)

? Credit Points : 10 ? SCQF Level : 10 ? Acronym : EEL-4-ELCEN

This course introduces students to the important analogue circuits of active filters, sine wave oscillators, relaxation oscillators, current sources, voltage references and phase-locked loops. The aim is to present and instill 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.

Summary of Intended Learning Outcomes

After successful completion of this course a student will
be able to:
- state the Barkhausen criterion for oscillation and to apply it appropriately to oscillator circuits;
- analyse and design oscillator circuits based on the phase shift oscillator, Wien bridge oscillator or Colpitts/Hartley oscillator and know how to stabilise oscillation frequency and amplitude without significant harmonic distortion;
- analyse and design a Schmitt trigger circuit and apply it to a relaxation oscillator to generate square or triangle waveforms (including voltage-controlled architecture);
- analyse and design simple voltage reference circuits based on Zener diode references, JFET pinch-off references and simplified VBE (bandgap) references;
- analyse and design phase-locked loop circuits based on a first order loop operating in the locked condition;
- demonstrate an ability to analyse the functionality of active filter circuits using standard nodal analysis techniques;
- describe the basic principles of active filter design (i.e. pass/stop band, cut-off frequency);
- describe and analyse the application of low pass filter approximations in the design of frequency sensitive circuits;
- use first and second order sections, to implement low pass, high pass filter responses;
- design low pass and high pass filters using the Butterworth and Chebyshev approximations;
- compare and contrast the main characteristics of the Butterworth, Chebyshev and Bessel approximations (pass band ripple, roll-off, phase response);
- describe the significance of component sensitivity analysis in the design of active filters.
