Abstract
Course on electronics for communication systems, including LNAs, mixers and oscillators. Analysis of the fundamental behavior of these circuits. Discussion of important principles such as matching, noise and non-linearity.
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.
