Abstract
Official abstract text for this publication.
A micro electro mechanical system (MEMS) oscillator supplies an oscillator output signal having a first frequency that differs from a predetermined frequency of the output signal. An error determination circuit determines frequency error from the predetermined frequency based on initial frequency offset and/or temperature and provides the error information indicating a difference between the first frequency and the predetermined frequency. The error information is used by a receiving system in frequency translation logic that utilizes the oscillator output signal as a frequency reference.
First claim
Opening claim text (preview).
What is claimed is: 1 . A method comprising: generating an oscillator output signal having a first frequency with a micro electro mechanical system (MEMS) oscillator; determining an error signal indicating a difference between the first frequency and a predetermined frequency; supplying the oscillator output signal and the error information to a receiving system; determining a frequency translation ratio of the oscillator output signal in the receiving system based on the…
