  • Abstract
    This paper presents a stable 4th order mismatch shaping technique using vector feedback dynamic element matching (DEM). When combined with a multi-bit sigma delta modulator, this DEM system allows high resolution band pass signals to be produced, using a low resolution unary weighted DAC.
