Title: Innovations of Seo Kyu Lee

Introduction

Seo Kyu Lee is a notable inventor based in Cheongju, South Korea. He has made significant contributions to the field of imaging technology, particularly in the development of CMOS image sensors. With a total of 2 patents to his name, his work has advanced the capabilities of image capturing devices.

Latest Patents

Seo Kyu Lee's latest patents include a CMOS image sensor that outputs signal data before reset data and a method for driving the same. This innovative CMOS image sensor comprises a pixel sensor, a data I/O line, a double sampling circuit, and an output circuit. The pixel sensor generates both signal data and reset data, where the signal data reflects the voltage level based on the amount of photo-charge produced from external energy. The reset data is generated during a reset mode. The data I/O line is responsible for transferring the generated signal and reset data. The double sampling circuit samples the signal data followed by the reset data from the data I/O line and drives an output terminal. The output circuit then outputs data related to the voltage level of the output terminal.

Another significant patent by Seo Kyu Lee is for a CMOS active pixel designed to improve sensitivity. This active pixel features a floating diffusion layer, a photo-diode, a reset circuit, and an output circuit. The floating diffusion layer, made of a first dopant type, receives signal charges generated by the photo-diode, which depends on the energy input. The photo-diode consists of first and second lower diode dopant layers of the first dopant type and an upper diode dopant layer of a second dopant type, with opposite polarities. The reset circuit manages the voltage level of the floating diffusion layer to a reset voltage level based on a control signal.
