A system and method for generating a pulse stream are disclosed. A ramp signal is generated. The ramp signal is compared with a Time of Transition signal to produce a result indicative of the comparison. Responsive to the result of the comparison, the pulse stream signal is output. The result of the comparison instructs the selector whether to maintain the current output pulse stream signal or replace the current output pulse stream signal with a Polarity signal.
