  • A stereo audio DAC with ground-centered class-D headphone drivers is fully integrated in a 45nm CMOS technology. [...] Key Method The asymmetric averaging PWM is also applied to improve linearity and suppress switching noise and loss. The measured SNR and DR are 103dB and 98dB, respectively.Expand Abstract
