Abstract :
The authors present a pipeline A/D converter with improved linearity (SNDR). The SNDR improvement is achieved through a combination of oversampling and mismatch shaping, which modulates the distortion energy out-of-band. At an oversampling ratio of four and 64, and a component mismatch of 0.1%, 9 and 35 dB improvements in SNDR are achieved, respectively, in comparison to a converter with no mismatch shaping
