Abstract :
This paper presents a first order noise shaped dynamic element matching (DEM) algorithm. The DEM algorithm was developed to improve the signal-to-noise and distortion ratio (SNDR) of a delta-sigma analog to digital converter (ADC). However, it can be applied to any system utilizing averaging and a plurality of unit components. Matlab simulations have shown that the presented algorithm eliminates idle-tones and provides almost a 30dB improvement in SNDR in a second order delta-sigma ADC.
