In the stereo audio DAC here presented, the trade-off between area-power consumption-S N R out-DR is optimized for the case of a 96dB audio system. Using a single-opamp SC structure for the reconstruction filter, a hybrid FIR/IIR transfer function allows to reject out-of-band noise. This circuit solution strongly reduces area and power consuption. In a 0.73μm CMOS technology the stereo DAC achieves a 97dB-DR and a 39dB SNRout with a 0.22mm2 area and 7.25mW power consumption per-channel. © 2004 IEEE.

Abstract

In the stereo audio DAC here presented, the trade-off between area-power consumption-S N R out-DR is optimized for the case of a 96dB audio system. Using a single-opamp SC structure for the reconstruction filter, a hybrid FIR/IIR transfer function allows to reject out-of-band noise. This circuit solution strongly reduces area and power consuption. In a 0.73μm CMOS technology the stereo DAC achieves a 97dB-DR and a 39dB SNRout with a 0.22mm2 area and 7.25mW power consumption per-channel. © 2004 IEEE.
