Abstract
A bias charge (commonly known as a 'fat zero') is divided into a plurality, n, of equal parts. These equal parts are differentially delayed, and the results appearing parallel in time are summed to generate a bias charge with reduced noise. The reduced-noise bias charge is then applied to an input of a charge transfer device -- e.g., one of the charge coupled device (CCD) analog shift registers used in a CCD imager to transport charge packets descriptive of picture elements in an imager.
