Design of low-voltage supply and reference block based on the bandgap reference
Mudroch, Michal ; Kledrowetz, Vilém (referee) ; Prokop, Roman (advisor)
In this diploma thesis there is elaborated design of low-voltage power supply block using I3T25 technology. The theoretical part describes the basic structures used in the design, using CMOS and bipolar devices. Furthermore, the properties and the analysis used in the evaluation are described. In the design part there is an elaborated design of individual parts, including voltage references, current references, DAC converter, operational amplifier. In the last part, the power supply block is subjected to simulations for verification of temperature compensated output variables and analyzed circuit functionality.

High-frequency oscillator in CMOS technology
Lang, Radek ; Musil, Vladislav (referee) ; Prokop, Roman (advisor)
This project focus to desing an on-chip oscillator in function as a clock generator. Frequency stability of the oscillator is affected by supply voltage, temperature and process variations. The aim is to propose a clock generator with sufficient frequency stability, low power consumption and a small chip area. This work deals with the types of oscillators and their basic building blocks suitable for our application. It also deals with the study and design options of temperature and process compensation circuit generating the current control, which provides the frequency stabilization of the output signal.

Weight Measurement with Bathroom Scale Strain Gauges
Šenfluk, Petr ; Fuchs,, Michal (referee) ; Povalač, Aleš (advisor)
The aim of the thesis is weigh measurement using strain gauges from cheap digital scales. Work describes problems connected with using strain gauges as temperature compensation and requirements for accurate voltage reference and summarize function and wiring of chaep digital scales using four strain gauges. Result of work is design of an electrical circuit for weigh measurement using four strain gauges from analyzed scale.

Functional analysis of circadian clock gene timeless in temperature compensation mechanism
SINGH, Samarjeet
This thesis is focussed on investigating the role of the circadian clock gene timeless in the temperature compensation mechanism in Drosophila melanogaster. To conduct the studies presented in this thesis advanced gene editing technique, CRISPR/Cas9, was used to target timeless and to create a variety of mutations. Application of various reverse genetics tools and behavioural methods described here contributed to the elucidation of timeless role in temperature compensation of the circadian clock.
