ABSTRACT:
An oscillator circuit is provided having an oscillating amplifier circuit connected to a resonator. The oscillator/amplifier and resonator are preferably fabricated on a single die using semiconductor fabrication tools. Included with the circuitry is a temperature sensor or transducer, an execution unit, non-volatile memory, a modulator, and frequency synthesizer, all of which are integrated together on the substrate, along with the piezoelectric crystal resonator. The frequency synthesizer can preferably include a phase-locked loop with a divider that is in a feedback loop of the phase-locked loop, in which a divide-by value is received from a modulator that achieves finer and higher resolution frequency selectivity from the voltage-controlled oscillator, also within the phase-locked loop, as an output from the crystal oscillator.
