ADC with variable duration of weighting cycles on the base of RPNS

Abstract

One of the perspective directions of ADC development is their construction using redundant positional notation systems (RPNS). Variable approximation cycle duration allows maximal usage of weight redundancy potential. The article contains structure of SAR ADC with variable cycle duration based on redundant positional notation systems of {0, 1} and {1, -1} types. The structure of device for generation of cycles with variable durations for this ADC is shown.
