Abstract
Disclosed is a circuit configured to apply a supply voltage to a switching element (e.g., a transistor). The circuit includes a latch and a processor. The latch is configured to sample a voltage of an output signal of the switching element, and the processor is configured to generate a power adjustment signal to adjust the supply voltage based on the voltage sampled by the latch.
Claims25
A circuit comprising:
- a latch operative to sample a voltage of an output of a switching element;
- a processor in communication with said latch and operative to generate a power adjustment signal indicating an adjustment to a supply voltage applied to said switching element, said adjustment based on said sampled voltage, said processor being further operative to generate a threshold voltage adjustment signal indicating an adjustment to a threshold voltage of said latch.
A method for adjusting a supply voltage applied to a switching element comprising:
- sampling a voltage of an output of said switching element with a latch;
- generating a power adjustment signal indicating an adjustment to said supply voltage applied to said switching element, said adjustment based on said sampled voltage;
- generating a threshold voltage adjustment signal indicating an adjustment to a threshold voltage of said latch.
A circuit for adjusting a supply voltage applied to a switching element comprising:
- means for sampling a voltage of an output of said switching element;
- means for generating a power adjustment signal indicating an adjustment to said supply voltage applied to said switching element, said adjustment based on said sampled voltage;
- and
- means for generating a threshold voltage adjustment signal indicating an adjustment to a threshold voltage of said means for sampling.
