Latest Patents

Makoto Ikuma holds a patent for a PLL circuit. This invention stabilizes the frequency of a first voltage-controlled oscillator in a PLL circuit part that receives a reference frequency signal. Additionally, a second PLL circuit part is created by inputting a control voltage, which matches the frequency control voltage of the first voltage-controlled oscillator, into a second voltage-controlled oscillator that has the same configuration as the first. The first PLL circuit part includes first and second variable frequency dividers that divide the reference frequency signal and the output of the first voltage-controlled oscillator, respectively. In response to an input signal into the second PLL circuit part, the free-running frequencies of the second and first voltage-controlled oscillators are switched, along with the division ratios of the first and second variable frequency dividers.
