LOW POWER OSCILLATOR SYSTEM

摘要

In a first aspect, an oscillator is disclosed. The oscillator comprises a digital circuit; and at least one Microelectromechanical system (MEMS) resonator. The oscillator includes a non-volatile memory, the non-volatile memory (NVM) storing a frequency value related to a resonant frequency of the at least one MEMS resonator. The digital circuit utilizes the frequency value stored in the NVM to provide a measure of real time from the MEMS resonator. In a second aspect, a system is disclosed. The system includes a processor and at least one Microelectromechanical system (MEMS) resonator operating at first frequency. The system also includes a memory. The memory storing a frequency value related to a resonant frequency of the at least one MEMS resonator. The frequency value is measured by an outside source. The processor utilizes the frequency value stored in the memory to provide a measure of real time from the MEMS resonator.
