CMOS Design for Optoelectronics Application
This is a one semester course involving lectures, projects and exams.
Basic core undergraduate courses in electronics, i.e, familiarity with CMOS and circuit analysis, and computer-aided design tools for circuit design such as Cadence.
By the end of the course, it is expected that students will be able to:
- Understand the basics of silicon photonics and optoelectronics
- Analyze and design CMOS circuits in particular for photonics applications
- Design a silicon-photonic CMOS circuit, including necessary test structures
- Learn Cadence and Lumerical tools
Detailed Course Outline
- Overview: Silicon photonics enables the fabrication of CMOS circuits for optical communications, sensors, and biomedical devices. Example components include modular and laser drivers, trans-impedance amplifiers, automatic gain control and temperature control circuits.
- Common circuit blocks: opamps, references, stability, etc.
- Compact models for optical devices: phase shifter (pin, thermal, etc.), ring modulator, detector
- Optical Link budget analysis
- Receivers: Basic concepts, limiting receiver, linear receiver, Trans-impedance Amplifier (TIA) Design; Limiting Amplifiers; Input offset cancellation; AGC techniques
- Transmitters – Modulator drivers, termination, bias control
- Laser drivers
- Tuning circuits
- Packaging considerations – wirebond/bump and package parasitics
- Fabrication technology description, design rules, process details
- Experimental methodoloty
- Clock and data recovery
- Computer-aided design (CAD) tools will be used for the modelling and design of CMOS circuits. These CAD tools include circuit stimulatin and layout (Cadence) and photonics design (Lmerical)
