Abstract
Course on electronics for communication systems, including low noise amplifiers, mixers for modulation and demodulation, transmit amplifiers and oscillators. Principles of wireless receiver, transmitter and frequency synthesizer. Analysis of the fundamental behavior of these circuits. Discussion of important principles such as matching, noise and nonlinearity.
Objective
Foundation course for understanding modern electronic circuits for communication applications.
Content
Introduction, review of bipolar and MOS devices. Basic amplification stages - Emitter and source coupled structures; Non-linear analysis, distortion and intermod.; Distor- tion in feedback amplifiers; C-E ampl. with shunt feedback, C-E ampl. with Emitter feedback; Basic output structures. Stability of feedback amplifiers, effect of feedback on gain, input and output imp. . Transformers and their applications in radio circuits, tuned circuits in bandpass amplifiers, im- pedance matching and matching networks, bandpass amplifiers. Elec. oscillators, insta- bility and oscillation, freq. domain descrip- tion, amplitude limiting through bias-shift. The Colplitts osc., crystal controlled osc., re- laxation and voltage controlled osc., analog multipliers, mixers and modulators.
