ELEC70004 Analogue Signal Processing


Lecturer(s): Prof Pantelis Georgiou

Aims

This module aims to introduce you to analogue signal processing techniques that can be used to perform computation in the analogue front end prior to back end processing and/or communication, with the aim to increase signal integrity as well as reduce the power consumption of the system as a whole. This is particularly beneficial for biomedical systems and portable battery operated systems such as mobile handhelds whereby high dynamic range, computational bandwidth and power consumption is crucial.

Learning Outcomes

Upon successful completion of this module, you will be able to: 1. Explain the different analogue processing domains and analyse the analogue/digital trade off 2. Design and analyse fundamental circuits using Current mode Techniques (Translinear Synthesis, Current mode computation, Log-domain filtering, current conveyors) 3. Design and analyse fundamental circuits using Voltage mode Techniques (V-I, I-V converters, Wide range Transconductance amplifiers, Trigonometric Circuits (Tanh, Sinh, exponential) Comparators, Peak Detection) 4. Design and analyse fundamental circuits using Switch Capacitor Techniques (Integrators, Differentiators, Memory Cells, Correlated Double Sampling and Chopper Stabilization) 5. Design and analyse fundamental circuits using Spike domain coding (Integrate and Fire Neurons, Cortical computation) 6. Discuss a Case Study in Biomedical Electronics.
