Synopsis:

The goal of the subject is to make students familiar with the new trends and concepts in analog circuits with an emphasis on the applications in the digital system peripherals. Here, the stress is placed on the design and implementation procedures of Application Specific Integrated Circuits (ASICs). Current design trends are discussed, including the analysis and test of analog and mixed signal circuits. The course provides knowledge for the development and design of electronic systems taking into account the aspects of current manufacturing technology of integrated circuits.
