An image sensor includes image sensor cells generating an image signal in response to one or more control signals, and a first driver generating a first control signal. The first driver includes a first positive supply terminal connected to a first power supply node. The image sensor also includes a voltage generator generating a first voltage at the first power supply node, where the voltage generator includes charge pump cells to receive clock signals and to source charge to the first power supply node, a delay line including delay line elements generating clock signals, where a first charge pump cell receives a first clock signal generated by a first delay line element, where a second charge pump cell receives a second clock signal generated by a second delay line element, and where a delay between the first clock signal and the second clock signal is determined by the delay line.

Disclosed are improved methods, systems and devices for color night vision that reduce the number of intensifiers and/or decrease noise. In some embodiments, color night vision is provided in system in which multiple spectral bands are maintained, filtered separately, and then recombined in a unique three-lens-filtering setup. An illustrative four-camera night vision system is unique in that its first three cameras separately filter different bands using a subtractive Cyan, Magenta and Yellow (CMY) color filtering-process, while its fourth camera is used to sense either additional IR illuminators or a luminance channel to increase brightness. In some embodiments, the color night vision is implemented to distinguish details of an image in low light. The unique application of the three-lens subtractive CMY filtering allows for better photon scavenging and preservation of important color information.
