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.

Design of ultra-low current consumption precise voltage reference in 180 nm BiCMOS technology
Varhaník, Jiří ; Háze, Jiří (referee) ; Prokop, Roman (advisor)
The diploma thesis deals with the analysis of noise and accuracy of integrated circuits for temperature stable reference voltage sources. It also describes the individual noise sources. In the first part of the thesis, three variants for the implementation of the voltage reference were tested, with a summary of the achieved parameters. The second part of the diploma thesis deals with the design of the switching reference, including source and control signals. The results of the work are presenting simulated waveforms with a specified accuracy at low circuit consumption.
