| titleOfInvention | High-performance gating vernier type time digital converter |
| abstract | The invention belongs to the technical field of integrated circuits, and particularly relates to a high-performance gating vernier type time digital converter. The high-performance gating vernier type time digital converter comprises a phase-frequency detector used for detecting rising edges of two input signals and comparing frequencies, a mode judgment device used for automatically selecting a quantization mode according to the amplitude of the input signals, a quantization unit used for achieving first-step quantization through a single-bit DSSA structure and conducting second-step quantization on the input signals through Vernier GRO, a multiphase counter used for reading a quantization result of the Vernier GRO, a loop locking accelerating unit used for recording the number and the classification of the rising edges of the input signals in a TDC dead zone and correcting TDC output and an assessment logical circuit used for conducting summing operation on multiphase counter output and conversion of original complements is conducted on the TDC output according to a PFD output frequency comparison result. According to the high-performance gating vernier type time digital converter, the obtained resolution ratio of the time digital converter is high, the measurement range is large, and the sample rate is high. |
