Title: Innovations of Sung-Shik Yoo

Introduction

Sung-Shik Yoo is a notable inventor based in Palatine, IL (US). He has made significant contributions to the field of technology, particularly in the area of detection circuits and methods for mitigating noise in photodetectors.

Latest Patents

One of his latest patents is focused on a detection circuit and method to mitigate 1/F noise in single detectors and image sensors. This innovative circuit includes an input capacitor that stores charge based on a current received from a photodetector during a bias phase. The stored charge on the input capacitor is sampled during the sampling phase to determine the amount of light captured by the photodetector. A bias controller supplies a pulsed-bias voltage to the photodetector to generate the current. The bias controller effectively controls the current to a level below a predetermined threshold via the pulsed-bias voltage before the biasing of the detector and subsequent sampling of the stored charge is initiated. This method is crucial for mitigating 1/F noise in the photodetector.
