“…Therefore, the dependence of the 1σ noises on sensitivity is shown in Figure 10b, which depicts that the larger the sensitivity, the smaller the 1σ noise. This feature of the time domain sensor is consistent with that of a variety of sensors, such as a magnetometer for high-resolution magnetic resonance spectroscopy [35], biosensors [36], electrochemical sensors [37], and displacement sensors [38]. In other words, sensor noise can be lowered by improving the sensor sensitivity.…”

This paper characterizes the sensitivity of a time domain MEMS accelerometer. The sensitivity is defined by the increment in the measured time interval per gravitational acceleration. Two sensitivities exist, and they can be enhanced by decreasing the amplitude and frequency. The sensitivity with minor nonlinearity is chosen to evaluate the time domain sensor. The experimental results of the developed accelerometer demonstrate that the sensitivities span from −68.91 μs/g to −124.96 μs/g and the 1σ noises span from 8.59 mg to 6.2 mg (amplitude of 626 nm: −68.91 μs/g and 10.21 mg; amplitude of 455 nm: −94.51 μs/g and 7.76 mg; amplitude of 342 nm: −124.96 μs/g and 6.23 mg), which indicates the bigger the amplitude, the smaller the sensitivity and the bigger the 1σ noise. The adjustable sensitivity provides a theoretical foundation for range self-adaption, and all the results can be extended to other time domain inertial sensors, e.g., a gyroscope or an inclinometer.
