| 摘要 |
The present invention relates generally to a method and apparatus of producing a control pulse of an extended duration for use in a voltage regulator. A first logic gate receives a plurality of signals each representative of the voltage demand of one of the plurality of output blocks and produces a control pulse of a first duration. A plurality of delay circuits receives the control pulse and produces a plurality of delayed control pulses. A second logic gate receives the control pulse and the plurality of delayed control pulses and produces a control pulse of extended duration. The control pulse of extended duration may be used, for example, for temporarily sourcing additional current to an output terminal of the voltage regulator.
