    摘要： An apparatus and a method for compensating for a mismatch in temperature coefficients of two oscillator frequencies to match a desired frequency ratio between the two oscillator frequencies over a temperature range. In one embodiment of a temperature sensor, first and second oscillators of different temperature characteristics are coupled to a differential frequency discriminator (DFD) circuit. The DFD circuit compensates for the different characteristics in order to match a frequency difference between the first and second frequencies over a temperature range.

    摘要： A frequency-control circuit, which is configured to receive a first signal having a first untuned frequency from a first oscillator, and to alter one or more pulses of the first signal to tune an output frequency of an output clock signal to have an average frequency at the desired target frequency. In some embodiments, the frequency-control circuit receives a signal from a single oscillator to generate a calibrated, precise, and temperature-stable clock.

    摘要： A MEMS oscillator includes a resonator body and primary and secondary drive electrodes to electrostatically drive the resonator body. Primary and secondary sense electrodes sense motion of the resonator body. The primary and secondary drive and sense electrodes are configured to be used together during start-up of the MEMS oscillator. The secondary drive electrode and secondary sense electrode are disabled after start-up, while the primary drive and sense electrodes remain enabled to maintain oscillation.

    摘要： A frequency-control circuit, which is configured to receive a first signal having a first untuned frequency from a first oscillator, and to alter one or more pulses of the first signal to tune an output frequency of an output clock signal to have an average frequency at the desired target frequency. In some embodiments, the two oscillators of intentionally different frequencies are periodically switched at a duty factor, which is dependent on an absolute temperature, to generate a calibrated, precise, and temperature-stable clock.
