A low power imaging array has a plurality of pixels wherein each pixel converts an intensity of incident light into electrical energy. An operational transconductance amplifier is utilized in conjunction with the imaging array to process the image signals from the low power imaging array. The operational transconductance amplifier includes a current mirror stage with a current mirror gain factor. The current mirror gain factor is selected based on a pixel noise level introduced by the low power imaging array such that current mirror gain factor noise introduced by the current mirror gain factor results in an overall noise level that is less than or equal to a predetermined level.
