Title:
HIGH RESOLUTION TIME-TO-DIGITAL CONVERTER
Document Type and Number:
WIPO Patent Application WO2001069328
Kind Code:
A3
Abstract:
A time to digital converter (TDC) has a pair of digital oscillators. The periods of the oscillators differ by T DELTA . The oscillators are triggered by START and STOP pulses. A counter counts a number of pulses until reference points on the signals output by the oscillators coincide. Measurements may be made using a dual resolution method. Intrinsic jitter of the TDC can be determined by comparing sets of measurements in which the switch in resolutions is made at different points.
