PULSE-WIDTH MODULATION PIXEL SENSOR
This abstract first appeared for US patent application 20250126363 titled 'PULSE-WIDTH MODULATION PIXEL SENSOR
Original Abstract Submitted
a pulse-width modulation (pwm) image sensor is described herein. the pwm image sensor may have a stacked configuration. a top wafer of the pwm image sensor may have a charge-to-time converter and a logic wafer, stacked with the top wafer, may include a time-to-digital converter. the pwm image sensor may utilize variable transfer functions to avoid highlight compression and may utilize non-linear time quantization. a threshold voltage, as input to a charge-to-time converter, may additionally be controlled to affect light detection, dynamic range, and other features associated with the pwm image sensor.
