Department of Circuit Theory

Synopsis:

This subject offers an overview of modern analog circuits design and applications, especially in the field of analog signal processing. The first part is devoted to the current-mode continuous-time circuits and systems design. The second part is oriented to the discrete-time circuits. Based on SC and SI building blocks, discrete-time analog systems are presented. Typical applications in filter and converter design technique are shown.
