Abstract
The systems, methods, and devices disclosed herein relate to a bit-per-stage ADC. The bit-per-stage ADC extracts one or more bits at each stage and creates a residue so that succeeding similar or identical stages can extract more bits. The ADC uses a reflected binary output code so that a bit can be extracted by observing the sign (e.g., polarity) of an input. The residue can be generated by rectifying the input, multiplying it by two, and level-shifting it by half the span. The generation of the residue is achieved using capacitors and switches. This causes the ADC to have low power consumption and a small size.
