In this patent application (2024-056859) Canon is looking at improving the reliability of an SPAD sensor. A SPAD (Single Photon Avalanche Diode) sensor, operates by putting the diode into, yes, you guessed it – avalanche mode.
In loose terms, that requires a high negative bias voltage (somewhere around -50 to -100 volts), which causes the [. . . ]
