Title: The Innovations of Guy Yehudian

Introduction

Guy Yehudian is a notable inventor based in Kfar Saba, Israel. He has made significant contributions to the field of image sensor technology, holding a total of 4 patents. His work focuses on enhancing the capabilities of CMOS image sensors, which are crucial in various imaging applications.

Latest Patents

One of Yehudian's latest patents is a single-exposure high dynamic range (HDR) CMOS image sensor pixel with an internal charge amplifier. This innovative sensor utilizes a charge amplifier with a selectively coupled conversion capacitor to read a single photodiode charge during a multi-phase readout operation. The design allows for an overflow readout during the photodiode charge integration phase, preventing saturation and enabling accurate measurements under extreme exposure conditions. The final HDR image data is calculated by summing overflow image data with high-sensitivity and low-sensitivity image data.

Another significant patent involves an endoscope system using a CMOS image sensor that has pixels without an internal sample/hold circuit. This endoscope system features a very small area CMOS image sensor with only four pads, which simplifies the design and reduces the size of the endoscope housing. The system performs correlated double sampling (CDS) to generate analog reset level and signal level values, transmitting these values to the host device in a streamlined manner.
