AbstractThis paper presents a third order continuous-time (CT) delta-sigma (ΔΣ) modulator with a fast three-level feedback scheme. The proposed technique uses two decorrelated 1-bit quantisers to produce a three-level feedback signal without requiring a decoder in the feedback path thus enabling high-speed operation. An efficient dynamic-element matching technique is also implemented to mitigate the weak non-linearity induced by the element mismatch. Two different approaches of implementing this technique are investigated and behavioral simulations are presented.
