This paper reports on the implementation of a closed-loop readout concept for a vibratory MEMS gyroscope. The system is based on electro-mechanical (el.-mech.) ΔΣ-modulation and implemented on an integrated circuit (ASIC) with incorporation of a field programmable gate array (FPGA) for rapid prototyping. The sense loop exhibits two modulation stages for the detection of the Coriolis-signal and thus reduces the sampling frequency (fs) by a factor of 4 and 100 compared to bandpass- and conventional lowpass modulators, respectively. This concept enables the design of low-power interfaces with very low fs, reducing the power consumption in the analog and digital domain. Measurements results of the readout circuit are presented using a MEMS gyroscope,whichdemonstrates the functionality and competitiveness of the concept
