We have investigated the impact of circuit limitations on the design of an Asynchronous Sigma-Delta Modulator (ASDM). Specifically, the hysteresis, which is normally embedded during the quantization process, can be used to improve the performance of ASDM. A programmable hysteretic element was designed and implemented for the quantizer and tested in an ASDM circuit based on John G. Harris et. al. We have shown that modulating the hysteresis in the quantizer can provide a larger input frequency… CONTINUE READING
