The system prototype consists of miniature frequency shift keying (FSK) transceiver integrated with microcontroller unit (MCU) in one small package, chip antenna, and capacitive interface circuitry based on delta-sigma (SigmaDelta) modulator integrated with a on-chip temperature sensor. At the base station side, an FSK receiver/transmitter is connected to another MCU unit, which sends the received data or received instructions from a PC through a graphical user interface GUI. Industrial, scientific and medical (ISM) band RF (433 MHz) was used to achieve half duplex communication between the two sides. ShockBursttrade RF protocol has been used to achieve high data rate of 50Kbps. Gaussian frequency shift keying (GFSK) modulation scheme was adopted to ensure a reliable and high-speed digital RF link. A digital filtering has been used in the capacitive interface to reduce noise effects forming capacitance to digital converter (CDC). All the modules of the mixed signal system are integrated in a printed circuit board (PCB) of size 22.46times20.168 mm. The overall system supply voltage is 2.7V maximum","PeriodicalId":318768,"journal":{"name":"Proceedings of the International Conference Mixed Design of Integrated Circuits and System, 2006.

Despite of the growth of their scale they have to meet very demanding norms concerning availability and reliability. Taking into account these facts, high degree of automation is obligatory for several accelerator subsystems. This article aims at summing up the effort of improvement of expert system for RF-power station for the FLASH. The main purpose of this software is to facilitate operators with automatic driving the power supply subsystem. Owing to the high level of autonomy possessed by the software special care has to be taken to assure predictability and safety of AI-aided operation. To assure sound engineering foundations of the project, techniques that facilitate the reasoning about correctness and predictability its behaviour have been used. As a starting point of design finite state machine computational model has been chosen. After a couple of months of lighting with several approaches of the FSM design and facing state explosion problem new design emerged which is expected to be a lot easier to maintain and adapt to new requirements","PeriodicalId":318768,"journal":{"name":"Proceedings of the International Conference Mixed Design of Integrated Circuits and System, 2006.

The amplitude range of output signal can be scaled over a very wide range, what ensures compatibility with various electrode arrays of different size and geometry.
