In this work, we verified the operation of a multi-tap macro-pixel based ultra-high-speed CMOS image sensor. The pixel of this sensor consists of the multi-tap lateral electric field charge modulator (LEFM) that has 4 storage diodes. This scheme has advantages such as a high frame rate determined only by the in-pixel charge transfer speed and efficient image compression in the charge domain. Based on this structure, previously, a 22.4 µm pixel pitch image sensor was developed. This paper shows a new image sensor with a pixel pitch of 11.2 µm. It was confirmed that the shutter controller operated at 506 MHz. Simulation results showed that the sub-pixel resolution was obtained in image reconstruction from the compressed images. |
