摘要：

This paper proposes a new stable design strategy for 1-bit high order digital Delta Sigma modulator used as division controller for multi-standard fractional-N frequency synthesizer. This digital Delta Sigma modulator presents simplicity and low power consumption. Simulation results illustrate the Delta Sigma modulator good performances in terms of spectrum purity and accuracy.
