Computer models of what happens when light hits the pixels of a CMOS image sensor are so complex that each simulation can take days to run. Tim Hayes hears how recent advances in software and hardware ...

There is typically a compromise between speed and efficiency when designing silicon photodiodes. Now, researchers have exploited microstructuring to achieve fast and thin devices that are also ...

The three-transistor design or 3T Pixel is the simplest CMOS pixel architecture (Figure 1). One transistor is used to reset or precharge the photodiode while two more are used for video readout: one ...
