摘要： An integrated MEMS and IC system (MEMSIC), as well as related methods, are described herein. According to some embodiments, a mechanical resonating structure is coupled to an electrical circuit (e.g., field-effect transistor). For example, the mechanical resonating structure may be coupled to a gate of a transistor. In some cases, the mechanical resonating structure and electrical circuit may be fabricated on the same substrate (e.g., Silicon (Si) and/or Silicon-on-Insulator (SOW and may be proximate to one another.

摘要： Provided is a voltage controlled oscillator to which a switching bias technique is applied so as to lower flicker noise of a bias circuit and enhance phase noise characteristics, thereby reducing the overall chip area to make it possible to achieve integration. A common mode voltage applied to the bias circuit is negatively fed back to an oscillation waveform. Therefore, it is possible to stabilize the magnitude of the oscillation waveform of the voltage controlled oscillator with respect to a change in an external condition.

摘要： A substantially temperature-independent LC-based oscillator is achieved using an LC tank that generates a tank oscillation at a phase substantially equal to a temperature null phase. The temperature null phase is a phase of the LC tank at which variations in frequency of an output oscillation of the LC-based oscillator with temperature changes are minimized. The LC-based oscillator further includes frequency stabilizer circuitry coupled to the LC tank to cause the LC tank to oscillate at the phase substantially equal to the temperature null phase.

摘要： 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.

An exemplary apparatus to generate a harmonic reference signal includes a reference resonator, such as an LC-tank, and an amplitude controller. The reference resonator generates a first reference signal having a resonant frequency, and the amplitude controller maintains substantially constant a magnitude of a peak amplitude of the first reference signal. A common mode controller may also be included to maintain substantially constant a common mode voltage level of the reference resonator. A temperature-dependent control voltage also may be generated and utilized to maintain the resonant frequency substantially constant or within a predetermined variance of a calibrated or selected frequency.
