Efficient CTDSM based on GM‐C quantiser and improved dynamic element matching
2020
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 t…

Applied science

Engineering is the use of scientific principles to design and build machines, structures, and other items, including bridges, tunnels, roads, vehicles, and buildings. The discipline of engineering encompasses a broad range of more specialized fields of engineering, each with a more specific emphasis on particular areas of applied mathematics, applied science, and types of application. See glossary of engineering.

The term engineering is derived from the Latin ingenium , meaning "cleverness" and ingeniare , meaning "to contrive, devise".

Efficient CTDSM based on GM‐C quantiser and improved dynamic element matching
2020
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…
