Differential transformer for the current sensor in phase-sensitive detector circuit shortcomings, in accordance with the idea of digital signal processing, a new digital phase-sensitive detector design, signal processing and strict process mathematical analysis, given the realization of the diagram关键词:...
The bang-bang phase detector is typically found in analog-based SerDes systems where an edge of the eye sampler and a data sampler at the middle of the eye are used together to determine if the data sample is early or late. A sampler is a circuit that can determine if the input voltag...
XOR phase detector response waveforms It can be seen that using these waveforms, the XOR logic gate can be used as a simple but effective phase detector. As might be expected for such a simple circuit, there are a few drawbacks to using an XOR phase detector: The phase detector is sensiti...
