Abstract
A CMOS-based voltage signal amplifier is particularly useful for amplifying signals from a single photodiode, or a small set of photodiodes, within a large photosensitive imaging device. When the imaging device reads out image signals from a large number of photodiodes, each amplifier is selected for operation only within a very brief time window when the particular photodiode associated therewith is reading out. The amplifier of the present design is suitable for rapid power-up and power-down when it is selected and deselected.
