Abstract
A 2.7V 4mW per-channel 20-bit 48kS/s sigma-delta stereo audio DAC, integrated in a 0.13mum CMOS technology, achieves a dynamic range (DR) of 101dB and occupies an active die area of 0.82mm2. The transformed quantization technique is proposed to decrease tonal behavior generated in low order sigma-delta modulator and the circuit is implemented to operate with optimal current consumption. The measured SNR and peak SNDR are 102dB and 95dB, respectively
