摘要：

A new high order sigma delta modulator called MSCL (multistage closed-loop) is presented. It uses a global feedback to lower the sensitivity to circuit imperfections and no digital prefiltering is required before summing up the output of each stage. Stable modulators can be realised to the sixth order. Simulation and experimental results will be presented.
