Abstract
An analog-to-digital conversion system includes two quantizers having a least significant bit arranged in a parallel pair. An input circuit coupled to the quantizers provides an analog input signal to the quantizers. A dither generator coupled to the quantizers provides an analog differential dither signal for perturbing quantization of the analog input signal. A combiner coupled to the quantizers adds respective outputs of the quantizers to obtain a linearized digital representation of the analog input signal.
