Design and properties of low-frequency amplifier with vacuum valves
Piroha, Ladislav ; Musil, Vladislav (referee) ; Šandera, Josef (advisor)
The purpose of the bachelor’s thesis is explanation of theory and construction of low frequency tube audio amplifier with UV meter. Main focus is on history and development of vacuum circuits from its early beginning, on electrical parameters and applied physical principles. Explanation of operating characteristics of amplifier classes and comparison of vacuum tube sound acoustic performance against transistor amplifier one. Finally, there is build description of single ended amplifier class A.

Differential amplifiers with bipolar transistors
Vyroubal, Petr ; Boušek, Jaroslav (referee) ; Horák, Michal (advisor)
This bachelor thesis deals with the theory of differential amplifiers with bipolar transistors, an overview of the basic connections and inspection their properties with the help of computer simulation program OrCAD PSpice. The specific type of differential amplifier is carried out experimental measurements, which perform as verification of simulated properties. The aim of this work is to analyze and compare the results obtained using the simulation program and the results obtained by laboratory measurements.

Vacuum tube headphone amplifier
Musil, Tomáš ; Kledrowetz, Vilém (referee) ; Háze, Jiří (advisor)
This Bachelor’s thesis deals with design and realization of vacuum tube headphone amplifier working in class A. There is a closer look into operating principals of vacuum tube, most common types, basic ways to use it in electronic circuit, designing stabilized power supplies and also realization of functional prototype and measuring it’s parameters.
