Increasing Sensitivity of CMOS Image Sensor.

[david cowan]

Hi,

I'm engaged in a low light level application and I'm looking to
increase the sensitivity of an image sensor by:
1. Slowing the clock radically to allow more charge to accumulate.
2. Obtaining a direct ANALOGUE signal from the sensor to allow me to
digitise it with much higher resolution.

In principal these devices are incredibly sensitive but unfortunately
(for me )the tend to be aimed at high speed applications. I need only
moderate resolution.

Any thoughts or anyone know of such a device???

Thanks again,
