  • Publication number: 20190165730
    Abstract: A compensation module, an oscillation circuit and associated compensation method for reducing an oscillation frequency variation in an output oscillation signal of a voltage-controlled oscillator (VCO) core are provided. The compensation module includes a compensation circuit and a polarity selection circuit. The compensation circuit has a capacitance value related to voltages of a first and a second receiving terminals. The oscillation frequency variation is changed with the capacitance value. The polarity selection circuit conducts a periodic regulated signal to one of the first receiving terminal and the second receiving terminal. The polarity selection circuit conducts a filtered bias signal to the other of the first receiving terminal and the second receiving terminal. The periodic regulated signal is sensitive to a regulated voltage variation, and the filtered bias signal is insensitive to the regulated voltage variation.

  • Patent number: 10236683
    Abstract: A voltage of a first pin that is one of several pins of an external connector of a system is measured, while the first pin is un-driven except for being pulled to ground through a first resistance, and a second pin of the external connector is being used as a power supply rail of the system. The measured voltage is compared to a short circuit threshold and in response to that threshold being exceeded, the power supply voltage on the second pin is reduced. In such an embodiment, no test stimulus needs to be applied to any of the pins of the external connector. Other embodiments are also described and claimed.
