ABSTRACT:
A circuit with reduced power consumption comprises first and second circuits that each have periodic active and inactive phases and that switch between the periodic active and inactive phases during operation. When the first circuit is in the active phase, the second circuit is in the inactive phase, and when the second circuit is in the active phase, the first circuit is in the inactive phase. A power supply communicates with the first and second circuits and generates first and second bias signals. The power supply selectively generates the first bias signal for the first circuit during the active phase of the first circuit, the second bias signal for the second circuit during the inactive phase of the second circuit, the second bias signal for the first circuit during the inactive phase of the first circuit, and the first bias signal for the second circuit during the active phase of the second circuit. The second bias signal is less than the first bias signal.
