The tester semiconductors device
Čala, Martin ; Čejka, Miloslav (referee) ; Havlíková, Marie (advisor)
Theoretical part of the bachelor thesis describes ATE systems focused on electrical tests of semiconductor diodes. There are also described key features of measured devices. In the practical part of bachelor thesis, there are described analysis made before design and realization own tester capable of recognizing unknown semiconductor diode and displaying selected static and dynamic parameters via text and graphical output. Whole system is based on Elvis II+ platform. Controlling application is made using MATLAB.

Nonlinear circuit structures using current and voltage conveyors
Gabriel, Viktor ; Hanák, Pavel (referee) ; Koton, Jaroslav (advisor)
This thesis deals with the use of active components in nonlinear circuits. First the variants of the current and voltage conveyors are theoretically described. Then the thesis deals with the design of the new curcuit structures with nonlinear components, which comes out from the former known realizations. Several possible solutions of the examined circuit have been designed and the most convenient structure has been selected. The chosen solution has been thoroughly analysed in subsequent diploma thesis to enable comparison of the theoretically designed circuit with the practically realized one.

Measurement and analysis of the detector preamplifier
Temel, Aleš ; republic, David Novák - FEI Czech (referee) ; Klusáček, Stanislav (advisor)
This paper investigates noise characteristics of detector preamplifier in electron scanning microscopes. Various preamplifiers are measured and the lowest noise level amplifier with good level of speed is used. Further measurement of individual levels of amplifier is done and proposed the most suitable way how to achieve the total amplification. By detailed measuring of amplifier structure are found all unpleasant factors that affect the image quality. On the basis of these dates amplifier hardware is adjusted, software solutions to improve image quality designed and model control implemented, which directly controls active elements of preamplifier so that noise for given amplification was the lowest and reached required amplification.
