This dissertation thesis deals with design of new functional blocks usable in area of analogue signal processing, focusing on sensor signal processing. Versatility of these circuits will find applications in programmable analogue array structures that will be possible to control and configure via a digital signal. Hereby build-up array would be fully a reconfigurable digital control system for sensor signal processing and usable for a wide range of different sensors. It offers possibility to build-up a control code for each specific sensor system, with which it would be possible to achieve optimal results of the entire system and consequently place the system on a chip. The presented programmable array is designed from configurable analogue blocks. The current feedback circuits, which in a suitable configuration can operate in voltage or current mode, are used here. This allows to achieve very good results in the systems with very low power supply, which is closely associated with mobility and autonomous behavioral (that are very important and observed parameters today) of the entire sensor-based framework. The work deals in detail with particular blocks, which are described theoretically and evaluated for using in the programmable analogue array. Design of the structure of programmable analogue array as well the use of these circuits in the part of whole system (that will be realized on a chip) are presented at the end of this thesis.
