Title: The Innovations of Pengting Zhang

Introduction

Pengting Zhang is a notable inventor based in Shanghai, China. He has made significant contributions to the field of image sensor technology. With a total of 2 patents to his name, Zhang continues to push the boundaries of innovation in his industry.

Latest Patents

Zhang's latest patents include an "Image sensor global shutter supply circuit with variable bandwidth." This invention features a pixel cell that includes a photodiode to accumulate image charge. A global shutter transistor is coupled to the photodiode to reset the image charge in response to a global shutter control signal. The global shutter control signal generator circuit generates the global shutter control signal to have a first value signal or a second value signal. The first value signal is coupled to turn on the global shutter transistor to reset the photodiode, while the second value signal controls the global shutter transistor to be in a low leakage off mode. A supply circuit is coupled to provide the second value signal to the global shutter control signal generator circuit, which includes a variable filter circuit to selectively vary a bandwidth of the second value signal in response to a bandwidth select signal.

Another significant patent is the "Global shutter control signal generator with reduced driving requirements." This invention also features a pixel cell that includes a photodiode disposed in a semiconductor material to accumulate image charge in response to light. A global shutter transistor is disposed in the semiconductor material and selectively resets the image charge in the photodiode in response to a global shutter control signal. The global shutter control signal generator circuit generates the global shutter control signal to have a first value, a second value, and a third value. The first value of the global shutter control signal turns on the global shutter transistor to reset the photodiode, while the third value controls the global shutter transistor to be in a low leakage off mode. The second value of the global shutter control signal is between the first and third values and turns off the global shutter transistor.
