Abstract
The present invention relates to a single-to-differential signal transformation circuit which comprises a differential signal generation circuit which is operable to receive a single-ended signal and generate a pair of differential signals having a phase relationship associated therewith. The transformation circuit further comprises a phase analysis circuit operably coupled to the differential signal generation circuit which is operable to ascertain the phase relationship between the differential signals and generate a status indication associated therewith. In addition, a compensation circuit is operably coupled to the phase analysis circuit and is operable to alter a function of the transformation circuit based on the status indication from the phase analysis circuit such that the altered function causes the phase relationship of the differential signals which form a circuit output to be closer to 180 degrees than an initial phase relationship generated by the differential signal generation circuit. In such a manner, improved differential signal phase balance is achieved.
