PLL-SCHALTUNG |
摘要 |
A PLL circuit with a series coupling of a charge pump, a loop filter and a voltage-controlled oscillator generating an output frequency (f), the voltage-controlled oscillator including tunable devices controlled by a first control signal generated by the loop filter, the PLL circuit includes a leakage compensation circuit for generating a leakage compensation signal to modify a control of the voltage-controlled oscillator, the leakage compensation signal being indicative for a leakage current in the tunable devices of the voltage-controlled oscillator. |
