  • Patent number: 10277122
    Abstract: A charge pump circuit and a phase-locked loop (PLL) system using the same are provided. The charge pump circuit includes an upper current source, a lower current source and a plurality of switches. The switches are turned on or off by an error signal to increase or decrease the control voltage of the voltage-controlled oscillator (VCO) and further control the frequency of the output signal of the VCO. When the reference frequency signal matches with the divided frequency signal from the VCO, the upper current source and the lower current source are bypassed to decrease the voltage across the MOSFET, thereby minimizes the influence of the leakage current on the control voltage of VCO. In this way, the output jitter can be reduced due to smaller magnitude of peak-to-peak voltage on the control voltage of VCO in the PLL system caused by the leakage current of the MOSFET.

The lithium battery control circuit includes a smooth transition circuit and an off-time control circuit. The smooth transition circuit generates a first voltage according to a sense current signal and a feedback signal, and generates a second voltage according to a mode signal. The smooth transition circuit compares the first voltage with the second voltage to generate a reset signal. The off-time control circuit converts the feedback signal to generate a first current by a voltage-to-current mechanism, and generates a set signal by using the first current and a duty ratio signal. The invention may prevent a surge current and an oscillation phenomenon by the smooth transition circuit. A switching frequency and a ripple size of an output current are controlled by the off-time control circuit.
