摘要： A fraction part control circuit of a frequency synthesizer apparatus including a PLL circuit is of a plural-n-th-order delta-sigma modulator circuit for controlling a fraction part of a number of frequency division to a variable frequency divider of the PLL circuit. An adder adds data of the fraction part to an output data from a multiplier and outputs the resultant data to a quantizer through a second-order integrator. The quantizer quantizes input data with a quantization step and outputs the quantized data to the multiplier through a feedback circuit. The quantized data is used as data of the controlled fraction part. The multiplier multiplies data from the feedback circuit by the quantization step and outputs the resultant data to the adder. The fraction part control circuit periodically changes the data of the fraction part, thereby setting a frequency of an output signal from a VCO according to an average value of the period.

摘要： A frequency synthesizer device comprising a PLL circuit (9) and a frequency-division ratio control circuit (5). The PLL circuit (9) includes a phase comparator (1), a low-pass filter (2), a voltage-controlled oscillator (3), and a variable frequency divider (4). The frequency-division ratio control circuit (5) controls the variable frequency divider (4) such that a frequency division ratio of the variable frequency divider (4) is changed in time and a time average value of the frequency division ratio contains a value below a decimal point. Two different signals of an output signal fdiv of the variable frequency divider (4) and an output fdiv2 obtained via a delay element (10) are used as clocks of an accumulator portion (81) in the frequency-division ratio control circuit (5). The variation in the substrate potential and the variation in the power supply voltage generated by the operation of the frequency-division ratio control circuit (5) can be reduced, and the degradation of C/N of the frequency synthesizer can be suppressed.

摘要： A wireless apparatus includes a clock generation PLL circuit of a digital baseband section. A variable output regulator receives as an input a VCO control voltage for controlling an oscillation frequency of a VCO in the PLL circuit, varies an output voltage in accordance with the VCO control voltage, and supplies, as a supply voltage, the output voltage to a power terminal of a high frequency circuit, such as an amplifier. The VCO control voltage changes in accordance with temperature or process variations, and the supply voltage of the high frequency circuit is controlled in accordance with the VCO control voltage. For this reason, performance deterioration ascribable to the temperature or process variations can be compensated for.
