ABSTRACT:
In an inverting system, a reference V.sub.REF is coupled to an input of a predictor. The predictor has an output V.sub.P and a transfer function T.sub.P. An inverter of the inverting system has a pulse width modulator, a filter, and a transfer function T.sub.I. The transfer function T.sub.P is substantially equal to 1/T.sub.I. The inverter has an output V.sub.C, and the inverter is coupled to the output V.sub.P so that V.sub.C =V.sub.REF T.sub.P T.sub.I =V.sub.REF. In this manner, the output of the inverter tracks the reference without phase error.
