Abstract
A device includes a converting circuit, a buffering circuit, and a routing circuit. The converting circuit is configured to transform a single-ended input signal into differential output signals. The buffering circuit is configured to amplify the differential output signals. The routing circuit is configured to route the single-ended input signal to an output of the converting circuit and has a shorter signal propagation delay than the converting circuit.
