	Low-power wireless sensor node Pobiecky, Michal ; Koton, Jaroslav (referee) ; Krajsa, Ondřej (advisor) The main purpose od this thesis is to design wireless sensor node with emphasis on low power consumption. This device is firstly made of microcontroller Atmel ATmega328P and for transferring measured data XBee 802.15.4 or transceiver nRF24L01 is used. Subsequently there is a design with Atmel ATmega256RFR2 with integrated wireless part and Lightweight Mesh protocol. Special attention is given to sleep modes and lowering power consumption. For ATmega328P the measurement of these power modes is done. Detailed record
	ECG data recorder Hruškovský, Antonín ; Krajsa, Ondřej (referee) ; Burda, Karel (advisor) The master thesis deals with the issue of long-term ECG recording, used in medicine for monitoring of cardiac anomalies. Author focuses on explaning the general concepts in the first part. Author describes measuring methods and issues associated with measuring. Comparison of existing devices and design of solution with own features are in next chapter. Next is comparison and selecting of formats for recording measured data and description of device connectivity. In next chapter author focuses on hardware design and implementation of device. After that author describes software solution design for microcontroller, Bluetooth module and smartphone. Author introduces possible improvements for future generation of the device and then describes results of testing at the end of this work. Detailed record
	Preamplifier for biological signals processing Derishev, Anton ; Prokop, Roman (referee) ; Khateb, Fabian (advisor) The work deals with the design and optimization of amplifiers in CMOS technology with low supply voltage and low power consumption. The main aim is to design an amplifier to amplify the biological signal. The first part is a brief introduction to the theory of biological signals. The work also contains a brief description of the biological signal processing methods and their properties. The important part is the description of the methods to reduce the supply voltage of the amplifier. The practical part of this thesis focuses on the design amplifiers with low supply voltage and low power consumption. All active elements and application examples have been verified by PSpice simulator using the 0.18 µm TSMC CMOS parameters. Simulated plots are included in this thesis to illustrate behavior of structures. Detailed record
