  • A 2.4 V 16-bit stereo audio digital-to-analog (D/A) converter was implemented using a 0.35 /spl mu/m CMOS technology. The DAC utilize an interpolation filter, 1-bit 4th-order noise shaper, switched-capacitor (SC)-postfilter with double sampling switching circuit and achieved low power, high resolution from a single 2.4 V supply. The proposed double sampling capacitor switching technique of the SC-postfilter is applied to improve the signal-to-noise ratio (SNR) which is limited by sampling noise… CONTINUE READING
