Abstract
Compensation of a signal using resonators as well as related methods and devices are described. Some embodiments include methods and devices for performing frequency compensation on a signal.
Claims45
A device comprising:
- a primary resonating structure having a first output signal;
- a reference resonating structure;
- a comparison element configured to compare a characteristic of the primary resonating structure to a characteristic of the reference resonating structure and to provide an output related to a comparison between the characteristics;
- and
- a compensation circuit adapted to adjust the first output signal from the primary resonating structure based on the output from the comparison element.

A method comprising:
- comparing a characteristic of a primary resonating structure to a characteristic of a reference resonating structure;
- providing an output related to the comparison between the characteristic of the primary resonating structure and a characteristic of the reference resonating structure;
- and
- adjusting a first output signal from the primary resonating structure based on the output related to the comparison between the characteristics.
