摘要： In accordance with some embodiments of the present disclosure, an oscillator circuit comprises, a first pad associated with a first terminal of an oscillator and a second pad associated with a second terminal of the oscillator. The oscillator is configured to generate an oscillating signal and communicate the oscillating signal from the second terminal to a clock distributor coupled to the second pad. The oscillator circuit further comprises an oscillator gain element comprising an output node coupled to the first pad and an input node coupled to the second pad. The oscillator circuit also comprises a digital-to-analog converter (DAC) coupled to the first pad. The oscillator circuit additionally comprises a switching circuit coupled to the gain element. The switching circuit is configured to enable the gain element when the oscillator comprises a resonator and disable the gain element when the oscillator comprises a voltage controlled oscillating module.

摘要： An oscillator may include a crystal resonator, an active element coupled in parallel with the crystal resonator and configured to produce at its output a waveform with an approximate 180-degree phase shift from its input, a voltage regulator a voltage regulator coupled to the active element, a sum of thresholds circuit coupled to the input of the voltage regulator, and a temperature-dependent current source coupled to the input of the voltage regulator. The voltage regulator may be configured to supply a supply voltage to the active element, the supply voltage a function of a reference voltage received at an input of the voltage regulator. The sum of thresholds circuit may be configured to generate the reference voltage such that the reference voltage is process-dependent. The temperature-dependent current source may be configured to generate a temperature-dependent current such that the reference voltage is temperature-dependent.
