Voltage comparator circuit and usage thereof |
| 摘要 |
A circuit comprising a first power supply having a first voltage and a second power supplying having a second voltage, wherein said first and second voltages are different at least in some cycles of said circuit, a memory element, wherein said first and second power supplies are driven into said memory element, a voltage comparator having connected thereto said first and second power supplies, wherein said voltage comparator is an analog to digital converter configured to provide digital output indicting of a voltage difference over a predetermined threshold between said first and second power supplies, and a supply selector element, wherein said supply selector element is configured to disconnect said second power supply from said memory element in response to the digital output of said voltage comparator. |
