Analog Predictive Circuit with Field Programmable Analog Arrays

Cooperation of the analog and digital circuits and the embedded controllers as well as their industrial use and technical application has always been in the focus of my interes. In reconfigurable systems the effectiveness and quality of the analog circuit system can be maintained and modified by circuit or by changing the single element values. There are further advantages of the programmable analog circuit applications; more compact, more reliable, more flexible systems can be produced with better performance. It is especially beneficial if for programming we modify the function of a programmable analog circuit either giving a new topology or a new component parameter using the flexibility of the microcontroller. In the microcontroller environment we can use these FPAA circuit in different useful application as a predictive-, and a characteristic prediction circuit solution. We describe a control solution of an industrial machine control asa demonstration of applicability of microcontroller and FPAA circuit cooperation.
