That may be sloppy terminology too. Sensor read noise does not change at different gains (except perhaps in Aptiva variable sensitivity sensors) , but the contribution of ADC noise to the total RN can be affected by analogue gain in the PGA.

I think recent Exmor "sensors" have tightly integrated PGA & ADC stages "on-chip". What should these devices be called? Sensors? Sensor systems? Imaging systems?

I suppose it comes down to what you class as a sensor these days, with assemblies replacing individual components.

Dan.

I have always used "sensor" to mean "sensor and supporting hardware", but I suppose I should spell it out each time.

Sensor, supporting hardware and digital signal processing.
