Abstract
The present invention relates to a conversion circuit that converts a single-ended signal to differential signals. According to an embodiment of the present invention, crosstalk is avoided by insuring that none of the transistors in the conversion circuit are directly connected to ground. By not having a transistor directly connected to ground, ground current is avoided and crosstalk associated with ground current is eliminated.
