Design of class AB stereo audio power amplifier
Zatloukal, Tomáš ; Polák, Ladislav (referee) ; Brančík, Lubomír (advisor)
The following work deals with design of class AB low-frequency amplifier, which is appropriately supplemented by correction Pre-amplifier and inrush protection circuit. The original schematic from prof. Leach was edited to fulfill task and to be easily completed from discrete components. The result of this work is the final design of power amplifier and correction pre-amplifier, protection circuit for speakers and power supply. As a next part, the design of printed circuit boards will be described together with assembling and mounting of boards in a construction box. Power amplifier will be verified by simulation and hardware measurements.

Quadrophonic audio amplifier for home use
Gavlák, Antonín ; Kratochvíl, Tomáš (referee) ; Brančík, Lubomír (advisor)
This bachelor work describes the design quadraphonic audio amplifiers for home use that works in class AB. The proposal includes a correction preamplifier integrated circuit LM1036 and power amplifier monolithic integrated circuit LM3886 to the output impedance of 8 with appropriate cooling power element. The work also deals with suitable power supply units and soft start circuit for the amplifier. The work contains materials for the construction of a functional prototype of the low-frequency power amplifier and the results of laboratory measurements.
