Abstract
The design of Continuous-Time (CT) Sigma-Delta modulator obtained by a discrete-time prototype is discussed. A proper heuristic transformation of the prototype enables an exact equivalence of CT and DT. This permits the trimming by computer simulations of the coefficients of the CT to account for the effect of real analog blocks. Simulation results for a second and third order scheme with real DACs verify the proposed methodology.
