Abstract
A converter () adapted to convert an analog input signal into a digital output signal includes an analog input terminal () for receiving the analog input signal, a Redundant Signed Digit (RSD) stage () coupled to the analog input terminal, and a digital section (). The RSD stage is configured to receive the analog input signal at the analog input terminal, produce a first number of bits at a digital output from the analog input signal during a first half of a first clock cycle, provide a residual feedback signal of the analog input signal at the analog input terminal during a second half of the first clock cycle, and produce a second number of bits at the digital output from the residual feedback signal during a first half of a second clock cycle, the second number of bits less than the first number of bits.
