Course Description
Analog circuits are increasingly part of larger chips containing both analog
and digital circuits. In this course, we look at the architecture of these
chips, the representation of signals in the analog and digital domain, filtering,
conversion with analog/digital and digital/analog converters. Constraints such
as maximum signal handling capability, electronic noise, frequency limitations,
and tradeoffs among these factors are discussed. Variety of communication
systems utilizing analog-digital interface circuitry is covered. The key concepts
discussed in the course are:
Areas of discussion:
- Filters
- Continuous time
filters- biquads and ladder type filters
- Biquads & ladder
- Opamp-RC,
Opamp-Mosfet-C, gm-C filters
- .Automatic frequency
tuning
- Switched capacitor
(SC) filters
- Data Converters
- D/A converter
architectures
- A/D converter
- Nyquist rate ADC-
Flash, Pipeline ADCs,….
- Oversampled
converters
- Self-calibration
techniques
- Communication systems utilizing
analog/digital interfaces
- Wireline communication
systems- ISDN, XDSL…
- Wireless communication
systems- Wireless LAN, Cellular telephone,…
- Disk drive electronics
- Fiber-optics systems
CAD Tools
The simulation tools used are SPICE (Hspice, Spectre)
and Matlab . This course
complements EECS 240, a
transistor level mixed circuits course.
Prerequisites
A basic course in signal processing (Laplace and
z-transform, discrete fourier transform) such as EE120 and fundamental circuit
concepts as taught in EE105 and EE140. Familiarity with Matlab and SPICE will
help.

No single book covers all the topics addressed in this course. The texts
listed below expand on the subjects covered. None is required, though a
good subset will probably help you substantially should you choose a career in
mixed signal design.
