Static power digital potentiometer |
摘要 |
An improved method and system for providing power to digital potentiometers is provided by applying the static electric field of an adjacent modified, non-volatile memory cell to the wiper mechanism. During periods of power removal to the circuitry as a whole, the potentiometer maintains the selected resistance via this static power supply. |
