A 0.0075 mm2, 0.0139 FoM Double-Ring Vernier TDC with Vernier Arbiter Phase Calibration and Code Error Cancellation for 26 dB SFDR Improvement in ToF-PET
{{output}}
This work presents a PET-oriented double-ring Vernier time-to-digital converter (DRVTDC) that targets the timing-quantization block required in multi-voltage-threshold (MVT) and time-over-threshold (ToT) front-end readout for time-of-flight (ToF) positron emis... ...
