Synopsis:

The aim of subject is to develop student's knowledge of analog electronic circuits. Attention is devoted to the new ways of analog circuit design, current-mode circuits, current-feedback amplifiers, prospective linear and non-linear high- speed building blocks and converters. Modelling and simulation of such blocks is discussed. Modern methods of signal generation and PLL systems design and exploation are presented.
