Design of a low-noise operational amplifier with 1/f noise analysis
Koukol, Martin ; Kledrowetz, Vilém (referee) ; Prokop, Roman (advisor)
This thesis is divided into two main parts. The first part deals with the physical description of the MOS transistor noise, focusing on the 1/f flicker noise. The equations for flicker noise in weak and strong inversion in linear and saturation regions and the dependence on transistor dimensions have been derived. These dependencies were verified by simulation. The second part deals with the design of a low-noise rail-to-rail operational amplifier, on which noise analysis was performer and also verified by simulation. The proposed operational amplifier was verified across process and temperature.

Realization of noise generator
Kalánek, Jakub ; Hadinec, Michal (referee) ; Kubásek, Radek (advisor)
This work occupy practical realization noise generator. The first part is concentrated on description accidental signal. In the second are color and sorts noises. The third part is concentrated on usage noise in practices. In the fourth part are sorts sources noise. The fifeth part is concentrated on circuit design and design easy noise generator and test Zener diode and set work point.

Noise generator
Pospíšil, Miroslav ; Kubásek, Radek (referee) ; Fiala, Pavel (advisor)
The goal of bachelor’s thesis „Noise generator“ is circuit design and construction of noise generator. The first part is concentrated on description of random signals. There are circuits of noise generators in the second part. In the third part is example of utilization noise generator in microwave sensors. And in fourth part are designed circuit and made measurements.

Anyalyze of photovoltaic cell by noise diagnostic
Husák, Marek ; Sládek, Petr (referee) ; Vaněk, Jiří (advisor)
The master’s thesis deals with the noise diagnostic in the solar cells. Describes the main kinds of noises. The samples were quality and reliability screened using noise reliability indicators. The samples were surveyed by measuring the I-V characteristics, the noise spectral density as a function of forward voltage and frequency. It was calculated the noise spectral density as a function of forward current.

Current Fluctuations of Reverse-Biased Solar
Škvarenina, Ľ.
This paper presents mainly noise diagnostics of pn junctions local defects in a singlecrystalline silicon solar cells structure. Research consists of a non-destructive measurement methodology of reverse-biased junction in solar cells. Diagnostics of defect areas in this documents are based especially on measurement of noise power spectral density, measurement of the radiation emitted from defects in visible range and I-V characteristic measurement.
