  • Publication number: 20190363722
    Abstract: A PLL circuit of one embodiment has a structure for preferably setting the FV characteristic of an LC-VCO. The PLL circuit includes a voltage controlled oscillator, a phase comparator, a charge pump, a loop filter, and an FV characteristic adjustment unit setting the FV characteristic. The voltage controlled oscillator has an FV characteristic indicating the relationship between a control signal and a frequency and outputs an oscillation signal having a frequency corresponding to the control signal based on the FV characteristic. The phase comparator detects a phase difference between an input signal and the control signal. The charge pump outputs a corrected voltage value changed according to the phase difference. The loop filter outputs a control voltage value changed in response to corrected voltage value variations. The FV characteristic adjustment unit generates an FV characteristic control signal by a mean corrected voltage value.

  • Publication number: 20190363704
    Abstract: A duty compensation device of one embodiment has a structure capable of more accurately setting a duty of a clock within an appropriate range. The duty compensation device comprises a duty adjusting unit, a duty measuring unit, a controlling unit. The duty measuring unit generates a sampling clock of a frequency fn that is asynchronous to the clock over an n-th period Tn (n=1 to N and N is an integer of 3 or more), and obtains measurement information for specifying the duty of the clock by using the sampling clock. The controlling unit determines a control code to be given to the duty adjusting unit based on control code candidates obtained for each of the N periods T1 to TN and the control code candidates in which the duty specified by measurement information obtained by the duty measuring unit is within a predetermined range.
