AB  - Conventional sigma-delta digital-analog converters (DACs) have performance limitations due to the use of switched-capacitor filters. In this design, a continuous-time output stage is used to achieve 112-dB signal-to-noise ratio (SNR) in a small chip area. The problems of jitter sensitivity and rise/fall matching are avoided by using a 6-bit modulator with a segmented scrambling circuit, along with a dual return-to-zero circuit.
