Demodulation methods on fully FPGA-based system for resolver signals treatment

Their importance and reliability make resolvers key building blocks in flight control and navigation dynamics. This paper gives an overview of the different synchronous demodulation methods, for such devices and lists advantages and drawbacks for each one. A particular attention is given to implantation in the same device of both analog to digital converter (ADC) and algorithm. This true system on a chip (SoC) solution is realized by the fusion field programmable gate array (FPGA) from Actel Company.
