Abstract: The application specific paper describes a practical circuits and interface techniques for quasi-digital MEMS accelerometers. This design approach is based on the Universal Frequency-to-Digital Converter (UFDC-1) working well with any frequency-time domain sensors. Such design approach lets significantly simplify the design process, reduce time-to-market and production price and produce data acquisition and sensor systems with high metrological performances. Practical examples of direct interfacing of quasi-digital accelerometers to the UFDC-1 are given.
Keywords: universal frequency-to-digital converter, quasi-digital output, MEMS accelerometers, PWM, duty-cycle, UFDC-1.
