ABSTRACT:
An oscillator comprising a cascode configured device having first, second and third terminals, a plurality of resonators and first circuitry coupled between the plurality of resonators and the second terminal of the cascode configured device. The first circuitry is preferably operable as an evanescent mode buffer to compensate for changes in the capacitance of the oscillator during operation.
