Latest Patents

Gihwan Cho holds a patent for an "Analog-to-digital converter and image sensor including the same." This invention provides an image sensor that includes a pixel array with multiple active pixels. The analog-to-digital converter (ADC) within this sensor converts pixel signals from these active pixels into digital signals. The ADC features an input circuit that outputs a first signal with a ramp signal applied to the pixel signal. Additionally, it includes an inverter with a pull-up and pull-down transistor, which outputs a second signal by inverting the first signal. A code generation circuit then produces the digital signal based on this second signal. This innovative design enhances the performance and efficiency of image sensors.
