dc.description.abstract | Disclosed is a self-calibration device for calibrating a phase difference between output waveforms of a ring oscillator, comprising: a voltage-controlled oscillator adapted to adjust the transition time of an output signal according to an inputting of a control voltage for controlling the phase offset and generate the adjusted output signal; a divider adapted to divide a frequency of the output signal generated from the voltage-controlled oscillator by a fractional number to generate a plurality of output waveforms having different phases with them having an identical phase difference each other; a phase-locked loop (PLL) circuit adapted to correctly make a frequency and phase of the output signal of the divider coincident with those of a system clock, the phase-locked loop (PLL) circuit including at least a phase-frequency detecting means adapted to compare the frequency and phase of the output signal with those of the system clock and to output a result of the comparison; and a phase offset calibrating loop circuit adapted to generate a control voltage for detecting a phase offset between output waveforms of the voltage-controlled oscillator and controlling the detected phase offset according to the result of the comparison inputted thereto from the phase-frequency detecting means for application to the voltage-controlled oscillator. | - |
