This module develops analogue IC design techniques from basic components through to building blocks and finally on to systems such as operational amplifiers. Bipolar and CMOS design topics are covered. Example circuits and SPICE simulations are used throughout the module to reinforce the analogue IC design techniques presented. Practical issues surrounding analogue and mixed signal IC design and implementation are emphasised. The design of phase locked loops is given a separate treatment because of the importance of these circuits in deriving reliable clock signals and the unusual mixture of analogue and digital circuitry operating in the GHz region.
The module introduces the design of integrated analogue and mixed analogue and digital circuits and the use of CAD tools to simulate and evaluate such circuit designs. Students who have completed this module have the ideal background to study the AMI module on Analogue Design Using AHDLs.
Who can benefit?
The module is particularly appropriate for electronic designers entering the field of analogue and mixed signal integrated circuit design. You will have a good working knowledge of basic analogue and digital design and a requirement to learn how to re-engineer systems on silicon. Experience of relevant CAD tools is not essential as full instruction will be given. Some experience of VHDL is desirable but accompanying instructional material will be available. The module can be studied on its own or as part of a programme leading to a qualification.
The module aims to develop an awareness and understanding of:
- the complete analogue and mixed signal design flow
- use of analogue and mixed signal IC design tools and techniques
- analogue and mixed signal design principles influencing efficiency, reliability and robustness.
Bipolar and MOS device operation and modelling, including passive components.
Basic analogue IC blocks, including switches, active resistors, current sources and sinks, current mirrors, voltage and current references.
Operational amplifiers and comparators, including low power, low voltage, BiCMOS design techniques.
Advanced SPICE analysis and simulation techniques, including automated component sensitivity analysis and performance optimisation.
Current mode circuits including multiplier cells and analogue function generators.
Analogue and mixed signal systems, including switched capacitor circuits.
Digital-to-analogue and analogue-to-digital converters.
Practical issues surrounding high level partitioning and the implementation of analogue and mixed signal IC designs.
Phase locked loop design for ICs, including types of divider, minimisation of noise, and limiting factors. Practical issues of design for operation at GHz frequencies.
The module is expected to involve 150 hours learning time spread over 12 weeks. All study and assessment is carried out via the internet so there is no requirement to attend in person. The approach is substantially student centered, with tutor support by email and telephone on a one-to-one basis, although peer discussion is encouraged. Typically the generality of a concept is introduced in the online text and the student is then directed to a variety of information sources to research and analyse the subject area further, reflect and draw appropriate conclusions. Self-assessment questions (SAQs) throughout the module reinforce the concepts and help students to monitor their progress and the effectiveness of their study. The module includes practical work using remote access to industry standard software hosted centrally. The module is assessed by two assignments, weighted 30% and 70%. Each assignment includes practical elements and will involve design work based on realistic case studies.
