A hardware efficient 3-bit second-order dynamic element matching circuit clocked at 300MHz

Abstract

A robust and hardware efficient dynamic element matching (DEM) algorithm is developed and used to design a 4th-order bandpass (BP) mismatch-shaping circuit, moved inside the feedback loop of a 6th-order bandpass continuous-time delta-sigma modulator. This algorithm is based on a shortened tree-structured scheme (STDEM) which can assure a stable high order… (More)
