Abstract
A circuit to convert a single ended signal to differential signals is disclosed. The circuit has two paths with each of the two paths comprising a plurality of stages. The number of stages in each of the two paths is the same. A first path of the two paths includes a buffer stage and at least one inverter stage. A second path of the two paths includes at least two inverter stages. The buffer stage has a delay matched to that of a first inverter stage of the second path. The buffer stage comprises a first pair of transistors comprising a first transistor of a first category operatively connected to a first transistor of a second category with their channel connections being connected in series.
