摘要： The circuit compensates for phase error in the case of fractional-N-based PLL frequency synthesizers. All required actuating and reference signals are derived from the VCO frequency of the voltage-controlled oscillator by using an auxiliary phase-locked loop. The circuit is specifically applicable for HF-PLL frequency synthesizers using integrated circuit technology.

摘要： In a PLL circuit, the precharging function necessary for setting a required initial state of a VCO is achieved by an additional precharge pump inserted in parallel with the charge pump, or alternatively by multiplexers and inverters implemented directly with the charge pump. The precharging function being controlled in both cases by two control signals. PLL circuits according to the invention are applied, in particular, in integrated circuits of mobile transceivers, for example for GSM, PCN and PCS.

摘要： A phase-locked loop circuit is described and has a digital circuit section and an analog circuit section that are fed with different supply voltages. Control signals generated by the digital circuit section are conducted to the analog circuit section via level converters and therefore can control functions in the analog circuit section.

摘要： A circuit arrangement includes a phase locked loop configured to produce a controlled frequency. The phase locked loop has an actuating input and a control loop output, with it being possible to tap off the frequency at the control loop output. In addition, a frequency meter is provided, which is connected to the control loop output of the phase locked loop. The frequency meter is configured to measure the frequency of the phase locked loop. Finally, a computation unit is provided in order to determine a gradient associated with the phase locked loop and generate a correction value based thereon, wherein the correction value is employed to mitigate a deterioration in the loop bandwidth due to variations in the gradient.

摘要： In order to shorten the transient recovery duration, the phase-locked loop has a voltage-controlled oscillator providing an oscillator signal to a first frequency divider. The first frequency divider divides the frequency of the oscillator signal, generates a first divider output signal therefrom, and passes it to a phase comparator during the transient recovery duration of the phase-locked loop. Furthermore, a unit is provided, which, after the transient recovery duration of the phase-looped loop, divides the frequency of the first divider output signal and passes it to the phase comparator. The phase comparator compares the first divider output signal with a first reference signal during the transient recovery duration. The phase comparator compares the divided divider output signal with a second reference signal after the transient recovery duration. The output of the phase comparator is connected to the voltage-controlled oscillator via a controllable charge pump.
