This course addresses the synthesis of analog integrated circuits, that is the design and sizing at transistor level of the main analog electronics components integrated on Si, in view of applications in instrumentation, telecommunication, signal processing ...
This course aims at presenting the state-of-the art (architectural solutions, performances and limitations) and at further providing an advanced design methodology.
At the end of this course, the student will be able to :
- Derive the mathematical relationships between the performances of the main integrated analog functions and the sizing of the transistors of the circuits.
- Apply these concepts to the optimal synthesis of such circuits in CMOS technology.
- Use to this aim, the appropriate professional methodologies and software CAD tools.
- Analyze and develop a critical view on standard and advanced implementations proposed in the technical and scientific literature.
- Understand, compare, and discuss different solutions proposed for actual applications
- Analog modelling of the MOS transistor
- Operational and transconductance amplifiers
- Switched-capacitor filters
- Continuous-time filters (MOSFET-C, gm-C)
- Switched-current circuits
- D-A, A-D converters (incl. Sigma-Delta)
- Voltage- or current- controlled oscillators
The details of the internal achitecture and of the operation of analog CMOS basic blocks and circuits are studied in the cases of actual integrated systems. Design and optimisation strategies are derived in order to achieve the performance specifications of target applications. Advanced computer-aided analysis and synthesis techniques are introduced. Practical case studies are presented or implemented in the frame of exercice sessions.
