Latest Patents
One of Kouichi Mitani's latest inventions is a disk reproducing apparatus featuring an active wide-range PLL device. This innovative apparatus prepares two control voltages to be input to a voltage-controlled oscillator (VCO) circuit. The first control voltage is utilized to continuously change the oscillation frequency of the VCO circuit. The second control voltage is designed to continuously adjust the first control voltage and oscillation frequency characteristics. The invention also incorporates a phase detecting circuit that compares the phase of the data read from a disk with that of the output from the VCO. Additionally, a frequency detecting circuit compares the frequency of the data read from the disk with that of the VCO output. The system includes a first filter circuit for equalizing signals from the phase and frequency detecting circuits, and a second filter circuit that extracts only the low-frequency component from the first filter's output. The outputs from these filter circuits are used as the first and second control voltages, respectively, ensuring that the first control voltage remains at a predetermined level.
