(06 -
EM516) Basic Information
Course specification
Course is active from 12.10.2009.. Precondition courses
Students acquire knowledge in the field of the impact of noise on the operation of components and electronic circuits in general, the minimization of the component and electrical circuit noise. Students are able to combine theory, measurement and simulation approach to problem sovling. Students who complete the course are able to:
-understand the basic problems of component and circuit noise,
-measure and extract the component noise parameters from the automatically obtained measurement results,
-model the component noise and use the results in software packages for the electronic circuit analysis,
-design electronic circuits in order to reduce the impact of noise and improve performances Probability and random processes. Stohastic processes. Autocorrelation and spektral density of signal power. The overview of basic internal component noise (thermical noise, flicker noise, generacion-recombination noise...) Basic units (dB, dBm,...). Basic parameters of component noise (spectral density of noise power, spectral density of input noise power). The principle of extraction of noise component parameters from the whole circuit noise. The noise of measurement devices and their impact on the measurement values (noise floor, input noise, background noise...). Modeling of the noise component based on the automatically obtained measurement results. The parameters of quality assessment of passive and active electronic circuits in relation to noise (the signal/noise relationship-SNR, noise factor- NF...) and the improvement techniques. The NF of cascade circuits and circuits with a loss. The problems of noise in modern RF and MW circuits (the modern electronic circuits show considerable maket impact). The transistor amplifier noise and the principle of its minimization. The oscillator phase noise. The design of and oscillator with as little phase noise as possible. The mixer noise. The design of an improved mixer in relation to noise. The impact of noise on the transmitter/receiver depending of the modulation type (error probability- EP) The impact of noise on the operation of digital circuits. The protection of electronic circuits from external noise. The design of power switches. The grounding design. Lectures. Auditory practice. Computer practice. Laboratory practice. Tutorial work.
