Abstract
A current generating circuit generating a current relevant to a reference voltage. The current generating circuit has a reference clock generating circuit generating a reference clock signal which has a frequency relevant to the reference voltage. The current generating circuit has a phase locked loop circuit generating a calibration clock signal. The phase clocked loop circuit regulates the calibration clock signal so that the phase difference between the calibration clock signal and the reference clock signal is reduced. The current generating circuit has also an output circuit generating an output current according to the phase difference between the calibration clock signal and the reference clock signal.
