Drive and sense interface for gyroscopes based on bandpass sigma-delta modulators

This paper demonstrates a MEMS gyroscope system with extensive use of sigma-delta (ΣΔ) modulation in both, primary and secondary modes. The primary loop has a bandpass ΣΔ-digital-to-analog converter (DAC) driving the primary mass into resonance, which is implemented on a field programmable gate arra...
