Abstract
A floating point analog to digital converter having an exponent converter which divides the input signal successively one-half until the divided signal is within the range of a mantissa linear analog to digital converter. The exponent converter also generate a digital exponent representative of the division factor. The resulting divided signal is then digitized by the mantissa analog to digital converter. An output is thereby provided composed of a digital exponent and a digital mantissa. In one embodiment, the floating point converter is a charge mode converter suitable for direct interface to a charge mode device such as a CCD image sensor.
