Abstrakt v dalším jazyce:	The paper deals with a novel hybrid integrated system for capacitive pressure MEMS sensors. This system should be splitted into the two parts. One is novel integrated capacity-to-current converter (C/I) and the second is auxiliary part made from standard SMD devices. The C/I converter was designed in CMOS process with technology AMIS 0,7 um. The second part consists of the sigma-delta converter, microcontroller, communication and data bus. The designed system profits from the previous works, where the capacity-to-digital output converter AD 7745 is the main part of the processing stage. This converter is substituted by the novel C/I converter. The C/I converter with digital calibration handled in microcontroller provide almost the same accuracy and linearity as the mentioned AD 7745 converter, but with less complexity of the whole circuitries.
