Noise Analysis of Basic Circuits for Analog Signal Processing
Humpolíková, Michaela ; Sládok, Ondřej (referee) ; Kubánek, David (advisor)
The cause of noise in analog circuits is a problem of quality in output signals. There are many reasons of its occurrence, noise is caused by components connected into the circuit, and the assembly itself. This bachelor thesis summarizes the theoretical knowledge about noise analysis. Noise measurement in circuits can now be calculated with PSpice, the results are used for the design of low noise circuits. In the contained practical analysis of the circuits were achieved the results for the suitable designing of low noise circuits.

Module for detection of ionizing radiation
Matějka, Tomáš ; Džbánek, Lukáš (referee) ; Kubíček, Michal (advisor)
This thesis deals with design of detector of ionizing X-ray radiation. Conventional PIN photodiodes are used for construction of the detector. The thesis describes issue of using PIN photodiodes for X-ray and gamma radiation detection. Transimpedance amplifier is designed with two diferent modes of detection. Both amplifier variants are compared and their suitability for specific applications is discussed. The thesis describes principle of converting analog signals to digital and describes concept of bus for multiple detectors connection to central unit. Options for paralel data processing are discused in last part of thesis. The detector is implemented and measured values are compared with simulations.

Design of low noise Band Gap reference in BCD process
Kadaňka, Petr ; Prokop, Roman (referee) ; Kadaňka, Petr (advisor)
This diploma thesis focuses on noise analysis of different integrated circuits used for generating temperature stable reference voltage. All noise contributions are studied separately and there is shown a way of their minimization. Circuit using external capacitor with pre-charging system is chosen as the best solution. Output noise of all analyzed circuits is compared and characteristics of final band-gap reference are summarized at the end of the work.
