Realization of the high-end audio amplifier LEACH
Korvas, Miroslav ; Dostál, Tomáš (referee) ; Slezák, Josef (advisor)
The theme of my bachelor’s thesis is a realization of the high-end audio amplifier and it’s modification for the lowest distortion. Because it was not specified, I have decided to for realization of amplifier 100 W. I use modification of LEACH amp circuit for using ThermalTrak [5] transistors. My bachelor’s thesis describes problems of distortion and particular description of separate blocks of LEACH amplifier and their function. The practical part of the bachelor’s thesis contains heat sink design, measurements and simulations of the amplifier and their confrontation to theory. Technical documentation for realization of the ThermalTrak amplifier contains printed circuit board.

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.
