Voltage doubler design in 0,25 m CMOS technology
Synek, Ladislav ; Prokop, Roman (referee) ; Radhoštěm, Milan Valenta, ON Semiconductor, Rožnov pod (advisor)
This diploma thesis deals with the design of a partially integrated charge pump in 0.25 micron technology ACMOS. The work is divided into two main parts, theoretical and practical. The theoretical section describes in detail various topologies of higher voltage generation of a charge pump and selected methods of regulating the output voltage of charge pumps. The practical part deals with the the actual design of a charge pump together with the arguments for the choice of the TPVD topology and the type of the regulation. Three regulation methods of a charge pump were implemented, tested and are dealt with: Pulse Skip, Constant frequency and PWM. There are 3 sub chapters, each describing a different regulation method, defining all the key elements of the design of such a charge pump and the results of the simulations are discussed. Conclusion of the thesis summarizes the results of the design of charge pumps, comparing them on the basis of the chosen type of output voltage regulation.

Wireless temperature monitoring system
Synek, Ladislav ; Kadlec, Jaroslav (referee) ; Kuchta, Radek (advisor)
In this work wireless temperature monitoring system was designed and developed. System is composed from several IQRF modules (sensors), which are connected via control panel of sensor network to a PC. IQRF modules were developed by Microrisc Company. Control panel of sensor network is a device with LCD touch screen, developed by Microrisc as well. Measured temperatures can be displayed on control panel and PC. Whole system is possible to control from PC or via control panel. It is also really simple to add and remove sensors from the system. Wireless temperature monitoring system is useful wherever, where is necessary to measure and record several temperatures.
