It's just 5-page paper.

Abstract:
An oversampled digital-to-analog converter
(DAC) with a 100-dB A-weighted dynamic range is presented.
It uses a switched-capacitor (SC) array to transfer
the sampled charges directly into the headphone driver.
The overall DAC gain is precisely controlled by a novel
reference stage. A new dynamic element matching algorithm,
based on split-set data-weighted averaging (SDWA),
is used to improve the dynamic range and to reduce the
nonlinearity caused by mismatches in the multibit DAC.
