    Abstract: A method and apparatus for compensating for temperature variation in a phase locked loop (PLL) includes receiving an error signal by a controller in which the error signal representative of an instantaneous frequency difference between a reference frequency signal and an output frequency signal of a voltage controlled oscillator of the PLL, and determining when a voltage of the error signal is outside of a predetermined voltage range. When the voltage is outside the predetermined voltage range, the method includes generating a new digital compensation signal based upon a previous digital compensation signal, and converting the new digital compensation signal to be an analog compensation signal. The method further includes filtering the analog compensation signal by a filter to produce a filtered analog compensation signal, and adjusting the output frequency of the voltage controlled oscillator in accordance with the filtered analog compensation signal.

    Abstract: A semiconductor device contrived to prevent a reference voltage and a reference current which are supplied to a high speed OCO from varying with a change in ambient temperature and/or a change in an external power supply voltage and to reduce the circuit area of a power supply module. The high speed OCO outputs a high speed clock whose magnitude is determined by the reference current and the reference voltage. A logic unit adjusts the values of the reference current and reference voltage, according to the reference voltage and reference current trimming codes related to detected ambient temperature and operating voltage.
