A CMOS optical receiver with subtraction-based level shifter for high-definition digital audio interfaces

Research output: Contribution to journalArticle

Abstract

This paper proposes a cost-effective CMOS optical receiver with a level shifter to reduce pulse width distortion and design complexity in high-definition digital audio interfaces. In this design, a level shifter is introduced at the receiver, in order to improve digital audio quality by threshold convergence. Measurement results demonstrate that the implemented optical receiver in a 0.25-μm CMOS technology can successfully reduce pulse width distortion within -2% and circuit complexity.
