Title: Ben Dror and Photon-Counting Image Sensor Innovation

Introduction

Ben Dror is an inventor based in Ma'Ale Gamla, Israel. His patent work includes an image-sensor design for photon counting, and he is associated with Semiconductor Components Industries, LLC. His listed portfolio includes 1 patent.

Latest Patents

Ben Dror’s patent, “Photon counting image sensor,” describes an image-sensor pixel built around a single-photon avalanche diode (SPAD). An analog counter is coupled to the SPAD’s cathode, while a comparator receives a signal from a floating-diffusion node, a reference voltage, and a comparator clock signal from the analog counter.

The pixel can also include an analog memory circuit selectively connected to the comparator’s output. A read-enable switch connects that output to a storage node, and multiple capacitors can connect to the node through their respective switches. Together, these components support the pixel’s photon-counting operation and analog signal storage.

Career Highlights

Dror’s listed invention focuses on integrating photon detection, counting, comparison, and analog memory within an image-sensor pixel. This approach brings several signal-processing functions into the pixel architecture.
