摘要： PROBLEM TO BE SOLVED: To provide a pulse generator capable of enhancing phase balancing or the like of a frequency converter. SOLUTION: The pulse generator comprises an oscillator 3 and a selecting arrangement for selecting how many of a first group 13 of delay elements are connected in series for delaying an IF clock of the pulse generator. Identical delay elements 26 receiving the IF clock in inputs are connected in series to form a second group. A measuring circuit 27 repeatedly measures the delay provided by the second group, for example providing output pulses IP whose pulse width IPD is equal to the delay. Reference pulse generators 29, 30 generate a series of reference pulses RP, each of which has a duration equal with a fraction of the IF clock period. A charge pump/integrator 28 compares the measurement and reference pulses to generate an error signal that is fed back to timing delay control inputs of all the delay elements such that the widths of the measurement and reference pulses are made equal to each other.
