Integrated temperature sensor bipolar core
Fránek, Jakub ; Prokop, Roman (referee) ; Kledrowetz, Vilém (advisor)
Cílem této práce je popsat možné způsoby realizace teplotního senzoru na křemíkovém čipu v běžných CMOS výrobních technologiích a představit konkrétní implementaci analogového jádra teplotního senzoru využívajícího bipolární tranzistory ve výrobní technologii TSMC 110. Techniky jako chopping, dynamic element matching nebo trimování byly použity k navržení obvodů, jejichž simulovaná 3 přesnost měření je ±3.5 °C bez trimování nebo ±0.6 °C s po jedné trimovací operaci napříč vojenským teplotním rozsahem. Navržené obvody zabírají pouze 0.012 mm čtverečních plochy čipu a jejich celkové parametry jsou srovnatelné s výsledky současných publikovaných prací.
Deasign and development of programable notch filter for audio circuits
Dohnal, Jaroslav ; Prokop, Roman (referee) ; Háze, Jiří (advisor)
This thesis discusses harmonic distortion and its measurement in the audio bandwidth using notch and tracking notch filters. The first chapter defines harmonic distortion and ways how harmonic distortion can be measured. The second chapter describes different notch filter topologies and their realizations for use in an audio band. It also describes the tracking part of a tracking notch filter. The third chapter shows a design of a notch filter using the state-variable topology, board layout and a control module for this programmable notch filter. It also describes A/D converter with USB interface used for making measurements in chapter four.
Backup AC Power Supply
Szabó, Andor ; Musil, Vladislav (referee) ; Prokop, Roman (advisor)
The aim of this thesis is to design a step-up DC/AC converter, an inverter from 12 V to 120 Vrms, with a sinus output signal. The converter should deliver a continuous performance of 300 W and a double peak power output of 600 W. The supposed usage of this inverter would be as a back-up power source for the circulatory pump of the central heating in the case of power outage. The inverter is consisting of a T-type power section.
Universal Emulation Platform for Checking the Designs of the Integrated Circuits
Podzemný, Jakub ; Kledrowetz, Vilém (referee) ; Prokop, Roman (advisor)
This work deals with verification possibilities of integrated circuits, especially with hardware emulation. The first part of the text briefly describes designing process of an integrated circuit, which includes emulation using emulation platforms. The main part of this work deals with the innovation of the emulation platform, which is used by SCG Czech Design Center s. r. o. Possible ways to improve the current emulation platform are explored and further taken into account when designing a universal emulation platform. Last part of this work deals with functional verification of the proposed universal emulation platform. Functionality will be verified by emulation of the basic control functions of the NCP1246 circuit.
Design of voltage references in BiCMOS ONC18 process
Dušek, Samuel ; Prokop, Roman (referee) ; Šotner, Roman (advisor)

Design of a Sigma Delta AD converter for sensor applications
Pěček, Lukáš ; Prokop, Roman (referee) ; Kledrowetz, Vilém (advisor)
This diploma thesis deals with the design of a sigma delta AD converter for a sensor application of junction temperature measurement in the automotive environment. A modified continuous time current mode modulator structure was designed. Its advantage lies in shifting and extending an input voltage range to work with signals from 0 V to 1,2 with a high impedance input and a relatively low hardware complexity. The functionality was verified by a behavioral model in the Simulink environment and then by transistor level simulation in CADENCE environment using ONC18/I4T technology.
