Abstract
In this work, a fast and accurate statistical eye-diagram estimation method for high-speed single-ended channel including non-linear pseudo differential receiver buffer circuit is proposed. For accurate estimation, the analytical model of the pseudo differential receiver buffer output voltage that includes impacts of external noises is derived based on piece-wise linear approximated MOS I–V curves. Moreover, the calculation based on compact input set whose components are possible receiver input waveforms for one unit interval enables the proposed method to calculate BER within short time. Accuracy and fast estimation time of the proposed method are successfully verified by comparing to the transient simulation results.
