Abstract:
We present an ultralow-power high dynamic range (DR) image sensor dedicated to autonomous vision systems, produced in a back illuminated 65 nm/40 nm stacked process and based on a time-to-digital pixel with in-pixel A/D conversion and data memory. Key to the low-power consumption is a new in-pixel comparator without dc …
