16-bit Delta-Sigma DAC with cascade-of-resonators feed-forward modulator and interpolation filter with OCSD code
A 16-bit 5.6-MHz clock-rate digital to analog converter (DAC) achieves 96-dB signal-to-noise rate (SNR) in the 22-KHz band. The optimal canonic signed digit (OCSD) code is proposed in a multi-stage interpolator filter to achieve less hardware consumption. A third-order cascade-of-resonators feed-forward (CRFF) with zero optimization Delta-Sigma modulator has been developed to convert an oversampled digital signal into 1-bit code. A switch-capacitor (SC) analog filter is used to reconstruct the analog signal.
