OFD구조를 가지는 이미지센서의 픽셀설계와 신호검출회로 설계

High-performance CMOS image sensor is designed by using OFD(Over Flow Drain) architecture. According to the light intensity variation, we analyzed characteristic of the pixel output voltage. Simulation results show that proposed circuit has a more wide dynamic range of the pixel output in condition of 5V power supply compared with the conventional pixel.
