Sažetak:
This paper provides the mathematical analysis of the Schmitt trigger propagation delay influence on the Asynchronous Sigma-Delta Modulator (ASDM) output signal frequency spectrum. Beside the propagation delay, the Schmitt trigger slew rate impact has also been presented. Based on the mathematical analysis, a method for the Schmitt trigger propagation delay compensation has been proposed. The method is implemented by introducing hysteresis level amplitude modulation. The first-order ASDM simulation and measurement models have been proposed for the propagation delay influence to the ASDM output signal frequency and for the compensation method verification. The measurement and simulation results for the proposed method confirm the ASDM output frequency spectrum improvement.
