Title: Innovations of Jun Ohta in Photo Detection Technology.
Introduction
Jun Ohta is a notable inventor based in Kyoto, Japan. He has made significant contributions to the field of photo detection technology. His innovative work has led to the development of a unique photo detection device that enhances the functionality of pixel circuits.
Latest Patents
Jun Ohta holds a patent for a photo detection device. This device features a pixel that includes a photodiode, an overflow circuit, a first sensing circuit, and a second sensing circuit. The first sensing circuit is designed to charge and discharge a cathode capacitance by a photocurrent flowing through the photodiode. It amplifies the obtained voltage using a source follower amplifier, which is then outputted to a data line. The second sensing circuit also charges and discharges the cathode capacitance by the photocurrent from the photodiode and outputs the electric charge stored in the cathode capacitance via the data line. The pixel circuit is configured to switch between a first mode, where the first sensing circuit is active, and a second mode, where the second sensing circuit is active. This switching is based on the amount of light received by the photodiode. In the first mode, gain is controlled according to the light received, while in the second mode, the storage time is managed.
