Data conversion method based on negative β-map |
摘要 |
There is provided a data conversion method based on negative β-map suited for an A/D converter or chaos generator, that is adapted to an integrated circuit and capable of providing stable operation of the circuit. The data conversion method based on negative β-map includes a discrete time integrator 1 having an amplification coefficient s and a damping factor β, a quantizer 2 connected in series to the discrete time integrator 1, and a feedback circuit connected from an output of the quantizer 2 to an input of the discrete time integrator 1. |
