Abstract

See full text

Integrated circuit devices include a packaged MEMS-based oscillator circuit, which is configured to support bidirectional frequency margining of a periodic output signal. This bidirectional frequency margining is achieved using a first signal to synchronize changes in a frequency of the periodic output signal and a second signal to control whether the changes in the frequency of the periodic output signal are incremental or decremental. In particular, the oscillator circuit may be configured so that each change in the frequency of the periodic output signal is synchronized to a corresponding first voltage transition of the first signal and a voltage level of the second signal may be used to control whether the changes in the frequency of the periodic output signal are incremental or decremental.
