Virtually all digital, analog and mixed-signal ICs are now done in CMOS due to the technology’s extremely low power consumption, small size and immunity to noise. Low power consumption arises from the use of a two-transistor configuration resulting in zero power consumption except during brief transitions. Interestingly, the bulk of CMOS power dissipation arises because […]

Special architecture lets CMOS image sensors double saturation signal level, widen dynamic range, reduce noise
Sony Semiconductor Solutions Corporation (“Sony”) has succeeded in developing the world’s first*1 stacked CMOS image sensor technology with 2-Layer Transistor Pixel. Whereas conventional CMOS image sensors’ photodiodes and pixel transistors occupy the same substrate, Sony’s new technology separates photodiodes and pixel transistors on different substrate layers. This new architecture approximately doubles*2 saturation signal level*3 relative to conventional […]
