An analog-to-digital converter including an input that samples an analog input signal; circuitry for multiplying the sampled analog input signal by a sequence including -1 and 1; a conversion unit which converts the analog input signal into a monotonic digital output signal; and circuitry for multiplying the digital output signal by the sequence of -1 and 1 in phase with the first means to produce a mismatch shaped digital output signal. In another embodiment of the invention there is provided a method of analog-to-digital including sampling phases of an analog input signal; multiplying the sampled phases of the analog input signal by a sequence including -1 and 1; converting the analog input signal into a monotonic digital output signal; and multiplying in phase the digital output signal by the sequence of -1 and 1 in phase to produce a mismatch shaped digital output signal.
