Abstract
This paper presents a new digital method to improve the performance of the ΔΣ modulator. The proposed method uses a fuzzy line enhancer (FLE) to reduce the existing noise in the output of the modulator. The simulation results show 14 dB improvements in signal to noise and distortion ratio (SNDR) by using the FLE.
