High Frame-Rate VGA CMOS Image Sensor Using Non-Memory Capacitor Two-Step Single-Slope ADCs
IEEE Transactions on Circuits and Systems I: Regular Papers(2015)
摘要
This paper proposes a column-parallel two-step single-slope analog-to-digital converter (SS ADC) for high-frame-rate CMOS image sensors. The proposed two-step SS ADC circuit does not utilize an analog memory capacitor to store the value of the first ramp step. Instead, to handle problems such as the slope errors of the second ramp and the stored charge error from charge feed-through, it utilizes a...
