A method and a system are described for improving a dynamic range of a CMOS image sensor by pixel-embedded signal amplification. An electromagnetic radiation is incident for a predetermined duration on a pixel-array comprising of a plurality of photodiodes. The photodiodes release electrons in form of an input elect...
A method and a system are described for dynamic range enhancement in CMOS image sensors using charge-transfer amplification. The method involves resetting a pixel array and other nodes of the CMOS image sensor. It involves receiving light for a predetermined duration on the pixel array layered with photodiodes. It i...
A method and a system are disclosed for pixel-embedded signal amplification of a CMOS image sensor using multi-step voltage-gain enhancement. It involves activating a row of the CMOS image sensor by resetting switches SRST202, SH1201 and SH2 209 to charge nodes PD1, PD2, SD1, and SD2 to a pre-set voltage potential a...
The invention relates to a CIS technology that uses impulsive metrics and non-linear/higher order statistics to substantially reduce the random telegraph signal (RTS) noise.
