A bias voltage generation method was proposed for a pixel source follower amplifier which is suitable for high resolution and high frame rate complementary metal-oxide semiconductor (CMOS) image sensors. In this method, the local bias circuit in every column and the sample-and-hold function for the gate voltage of the load transistor were used to prevent shading and streaking noise, while realizing low noise and high speed performance of the pixel source follower. The theoretical noise analysis of an 8K 120 fps image sensor with the proposed method showed a low input-referred noise of 2.04 e^−, whereas, the conventional method showed noise of 2.57 e^−. |
