Photometry Electrical Circuits TRIZ Cases
- SPAD Pixel Active Quenching and Reset for Low EPP
Active quenching and reset in a SPAD pixel cut charge flow and afterpulsing while enabling lower energy per pulse and higher count rate.
- Integrated Visible and SWIR Image Sensor Pixel Architecture
A pixel-level layout combines a visible photodiode with a thin-film Schottky SWIR diode to enable dual-band imaging in one sensor.
- SPAD Image Sensor Photon Counting With Counter Overflow Timing
Using counter overflow timing, this SPAD image sensor estimates total photon counts with fewer bits to cut power while preserving image quality.
- Photomultiplier Tube Gain Calculation From Dark Pulse Signals
Dark pulse digitization lets a photomultiplier tube estimate gain without dedicated measurement circuits, simplifying hardware while preserving accuracy.
- P-Type Transfer Gates for Low-Power Light Detection Pixels
Using p-type transfer gates removes negative charge pump circuits, cutting pixel power and chip area while preserving dark current control.
- Peltier Sensor Package Layout to Block Foreign Matter Transfer
A recessed Peltier package with a ceramic interposer and sealed lid blocks dust migration to the sensor element and preserves airtight operation.
- SPAD Image Sensor Overflow Counting for Low-Power Photon Estimation
Overflow timing lets a SPAD image sensor estimate total photons with a smaller counter, cutting power without losing count accuracy.
