Course detail

Analog Electronics 2

FEKT-BPC-AE2Acad. year: 2022/2023

This course improves and extends gained knowledge from Analog electronics 1 in the area of practical analog circuit design and brings an amount of new areas that are essential for designers of analog electronic circuits. The circuits for signal shaping, basic transistor building blocks (current mirrors, differential pairs), design of single stage transistor amplifiers (including bias point), switching applications, guidelines of practical work with operational amplifiers and their specific nonstandard applications, comparative operations, flip-flop circuits and multivibrators, circuits for signal generation, etc. belong to the fundamental skills of bachelor students focused on weak current electronics. The solved examples at lectures are supported by computer (OrCAD PSpice, Snap, Matlab) and laboratory exercises.
