Time-To-Digital Converters TRIZ Cases
- Stochastic Time-to-Digital Converter for Linear Phase Measurement
Voltage-selectable arbiter cells expand time-offset combinations to improve stochastic TDC linearity and ultrafine phase resolution.
- Stochastic TDC Voltage Selection for Ultrafine Linear Phase Detection
Voltage-switched arbiter cells and binary conversion improve stochastic TDC linearity and ultrafine phase resolution despite mismatch.
- Metastable Ring Oscillator TDC Calibration for Timing Accuracy
Calibrating the delay chain compensates for manufacturing variations in circuit speeds, improving positron emission event positioning accuracy.
- Time-to-digital converter calibration using high-frequency reference clock
A time-to-digital converter system uses a high-frequency calibration clock signal to determine precise bin addresses for accurate time measurement.
- Time to Digital Converter Circuit Noise Filtering
A time to digital converter circuit uses an intermediate memory unit to store and compare time stamps for noise filtering.
- Time-to-digital converter asynchronous reset for time-domain bias
Asynchronously resets the input stage using independent duration intervals to eliminate time-domain bias from fixed measurement periods.
- Time to Digital Converter with Control Signal Gating for Start-Stop Order Errors
A time to digital converter uses a control signal to enable measurement blocks only after start signal activation.
- SPAD Array Image Sensor Chip Depth Measurement Noise Reduction
Merging SPAD units via decision circuits filters environmental noise interference while reducing data output delays for high-precision depth measurement.
- Clockless Time Interval Digital Conversion via Charge Redistribution
A clockless time interval conversion method maps electric charge to digital words using a sampling capacitor and redistribution array.
