Efficient CTDSM based on GM‐C quantiser and improved dynamic element matching
March 2020 • Anil Kumar Sahu, Vivek Chandra, G. R. Sinha, Neeraj Kumar Misra
In this study, a continuous‐time delta‐sigma modulator (CTDSM) is developed using a Gm‐C based noise‐shaping quantiser (Gm‐C‐NSQ) with an improved dynamic element matching (i‐DEM) algorithm. Here, a Gm‐C integrator is used to develop NSQ, since it increases the effectiveness of the proposed modulator in terms of power consumption and die area. This Gm‐C‐NSQ uses only three dynamic latches to provide efficient quantisation level and to increase the order of noise shaping. Moreover, an i‐DEM algorithm is utilised to…
