DIGITAL PHASE METER AND PHASE DETECTION METHOD

摘要

A broadband digital phase meter having a technique for phase detection is provided. The device measures the phase difference between the two signals and is suitable for integration into a single MMIC. The input signals are digitally compared using two EXOR gates and integrated over the phase comparison period. The resulting analog signals are digitized using an analog to digital converter. In addition, a 2xD-type register is used to resolve the (0 to 180 ) or (180 to 360 ) ambiguity of the EXOR phase detector.;
