In this paper a novel system concept for the implementation of low-power readout electronics for micromachined gyroscopes is described. The main innovation is a modified Chopper Stabilization (CHS) technique in a SigmaDelta loop based on an undersampling process. It enables the design of a full Continuous-Time (CT) SigmaDelta interface dissipating less power than its Discrete-Time (DT) counterpart without additional hardware effort for a flicker noise suppression. Further a systematic design approach for an interface employing this method and an architecture enabling this procedure is presented.
