A novel technique for achieving noise shaping in oversampled converters is proposed. It uses the adaptive algorithm to minimize the mean square quantization error. The circuit implementation looks like a sigma-delta modulator and requires limited additional circuits for the necessary multipliers. Simulation results, confirmed by experimental measurements, show that more than 15dB in the SNR are gained with respect to an equivalent sigma-delta counterpart in the low signal level range.
