|---|---|---|
A 640 × 480 indirect Time-of-Flight (ToF) CMOS image sensor has been designed with 4-tap 7-μm global-shutter pixel in 65-nm back-side illumination (BSI) process. With novel 4-tap pixel structure, we achieved motion artifact-free depth map. Column fixed-pattern phase noise (FPPN) is reduced by introducing alternative control of the clock delay propagation path in the photo-gate driver. As a result, motion artifact and column FPPN are not noticeable in the depth map. The proposed ToF sensor shows depth noise less than 0.62% with 940-nm illuminator over the working distance up to 400 cm, and consumes 197 mW for VGA, which is 0.64 pW/pixel. |
