“…11. To do so, a specific electronic circuit should be designed to implement the Q-factor measurement in time-domain [21]- [27]. After the detection of the mechanic vibration, the corresponding ring-down voltage can be expressed by (4), as shown in Fig.…”

“…In this design, apart from the Q-factor measurement, the ring-down signal is also used for the resonance frequency measurement by using a separate counter. Another way to count the pseudo-periods is proposed in [25]- [27], in which a peak detector is used and each detected peak is kept on a memory during the comparison with voltage reference. Only the periods whose amplitudes are lying between the two predefined references are counted for Q-factor calculation.…”

“…In order to increase the circuit operation frequency, we have designed the Q-factor measurement circuit in CMOS 0.35μm [27]. The circuit is designed under these conditions: a voltage supply of 5V, a Q-factor of almost 2000, and the two reference voltages chosen as 0.3V for V 1 and 2.2V for V 2 .…”

“…Finally, time-domain measurement is performed with an acquisition of transient response of the resonator under test to a single frequency excitation but the extraction of Q-factor is carried out by using a specific designed circuit or a specific signal processing in time domain via a PC computer [21]- [27]. If the circuit is implemented on the same chip as the resonator, the Q-factor measurement can be made in-situ and even during the application of the resonator.…”

A resonator is one of the important components in electronic systems. It is often used in an electronic system to give an accurate time reference. But it can also be used as a highly sensitive physical parameter sensor especially with the rapid development of fabrication technology for Micro Electro Mechanic System (MEMS) sensors. One of the parameters used to describe the performance of a resonator is its quality factor, also called Q-factor for short. Knowing the Q-factor of a resonator can make sure the performance of the system in which the resonator will be used. For applications in which a resonator is used as a sensing device, it is crucial for the Q-factor to be surveyed and measured in real time. In this paper, a review of a resonator's quality factor (Q-factor) measurement is given. Three major approaches can be identified from the literature: frequency domain, time-frequency domain and time domain. Both advantages and limitations of each approach are presented. Based on the published results, a comparison of the three approaches is conducted. As the time-domain measurement is the only way to present the potential for an in-situ Q-factor measurement but it is relatively less exploited compared with others, a special focus on the time-domain measurement is granted with two time-domain circuit designs.
