Abstract
An analog-to-digital converter, including a code generator, coupled to receive an input analog voltage and to one or more reference voltages, and adapted to generate a digital code responsive thereto, and one or more folded differential logic encoders (FDLEs) . Each of the FDLEs includes a plurality of capacitors and switching logic. The switching logic is coupled to receive the digital code and distribute a charge between the plurality of capacitors responsive to the received digital code, and to output a digital bit indicative of the input analog voltage responsive to a magnitude of a potential generated by the distributed charge on at least one of the plurality of capacitors.
