Paper Abstract

Despite the advances in digital signal processing, the analog circuits which amplify and define the bandwidth of the low level signals from CCD and IR array detectors are a critical element in obtaining the best possible signal-to- noise ratio. The choice of components and topology for these front-end circuits is discussed, including the effects of input voltage and current noise density, coupling strategies, shield driving, physical layout, and grounding. The signal chain use in Imaging Sciences Laboratory instruments is presented as an interpretation of these considerations.
