In this paper, a novel compensation method, Dynamic Stage Element Matching (DSEM), is introduced. This paper provides a comparison of existing error compensation methods and DSEM. DSEM extends Dynamic Element Matching (DEM) of Digital to Analog Converters (DAC) to entire stages of a pipeline ADC. Results show that the use of DSEM, when used in conjunction with Capacitor Swapping (CS) and DEM, increases the Spur Free Dynamic Range (SFDR) of a pipelined ADC by at least 3dB, then using CS or DEM alone.
