Title:
MEASUREMENT DEVICE AND MEASUREMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2020/140208
Kind Code:
A1
Abstract:
A measurement device (1) and a measurement method. The measurement device (1) comprises an oscillation circuit (11), a time average frequency-frequency lock loop (12), and a digital signal processing circuit (13), wherein the oscillation circuit (11) comprises an element to be measured and is configured to output a signal having an oscillation frequency associated with an element value of said element; the time average frequency-frequency lock loop (12) is configured to receive a signal output by the oscillation circuit (11), and to output a frequency control word associated with the oscillation frequency; and the digital signal processing circuit (13) is configured to read the frequency control word output by the time average frequency-frequency lock loop (12), and obtain the element value of said element according to the read frequency control word. The measurement device (1) is easy to be integrated, has small volume, low power consumption, and high reliability, and can implement high-precision measurement.
