“…Based on Random-Rotation-Binary-weighted Selection (RRBS) [11], this paper proposes a new DEM method which is capable of effectively reducing the glitch with much less area. To solve the complexity of design, this proposed DEM method uses the input data of DAC, which is random enough to replace original pseudo-random number generator (PRNG) [12,13,14]. In addition, data selector is used as a substitute for common glitch reduce structure, for the purpose of further reducing the complexity.…”

Due to the appearance of huge glitch while using traditional Dynamic Element Matching (DEM) in data converters, different kinds of glitch-reduce structures are designed into DEM. However, most of these structures will work with high complexity. Based on random-rotationbinary-weighted selection (RRBS), this paper presents a novel low complexity glitch-reduced DEM algorithm, which can greatly reduce mismatch. The proposed DEM constructs glitch-reduce structure through data selector and comparator, so the complexity is reduced through using less components. As a result, the glitch-reduced DEM increases spurious free dynamic range (SFDR) to 92.47dB at 7.6MHz. Moreover, compared with conventional RRBS, glitch-reduced DEM makes the glitch reduce by 49% with low complexity in a 12-bit digital-to-analog converter (DAC).
