【 摘 要 】

References(5)This paper proposes an automatic threshold converged CMOS optical receiver employing a threshold convergence technique to reduce pulse width distortion and design complexity in high-definition digital audio interfaces. A threshold concentrator is introduced at the receiver, in order to improve digital audio quality by aligning various logic thresholds of the input signals into a constant one. Simulation results demonstrate that the designed optical receiver in a 0.18-µm CMOS technology can successfully reduce pulse width distortion within -2% and circuit complexity.
