EEC211 - Advanced Analog Circuit Design
3 units - Winter Quarter
Lecture: 3 hours
Prerequisites: EEC210. Statistics 131A and course 112 are recommended.
Grading: Letter; based on homework, midterm and final exams
Noise and distortion in electronic circuits and systems. Application to communication circuits. Specific applications include mixers, low-noise amplifiers, power amplifiers, phase-locked loops, oscillators and receiver architectures.
After taking this course the student should understand:
- The origins of noise in electronic systems
- How to analyze circuits and systems with noise sources present
- How to design systems to minimize the deleterious effects of noise
- How to analyze distortion in memoryless electronic circuits
- The impact of combined noise and distortion on various communication circuits
Expanded Course Description:
- Review of necessary probability and statistics
- Noise as a random variable. Derivation of thermal noise voltage. Autocorrelation function. Power spectral density. Noise bandwidth.
- Non equilibrium noise sources: shot, flicker, burst, avalanche.
- Noise models for electronic devices. Equivalent input noise generators. Optimum source impedance.
- Signal-to-noise ratio (SNR) and Minimum Detectable Signal (MDS). Noise Factor (F), Noise figure (NF), Noise Temperature (Te). Available gain (G) and Noise Factor for cascaded stages.
- Effect of feedback on noise.
- Noise shaping circuits to improve SNR. Chopper amplifier example. (optional - as time permits)
- Low-frequency distortion analysis using series expansion. Definitions of distortion products.
- Effect of feedback on distortion.
- Distortion in cascaded stages.
- Distortion and noise in communication circuits, spurious-free dynamic range.
- High-frequency distortion and the Volterra Series. (optional - as time permits)
- Applications (cover as time permits)
- Low-noise amplifiers
