PROBLEM TO BE SOLVED: To easily make a frequency high so as to provide a suitable output waveform of the same frequency as the frequency of an oscillator. SOLUTION: This circuit generates a first comparator output 71 composed of a rectangular wave to rise at a prescribed value 81 in the up slope of a triangular wave 5 and to fall at a prescribed value 81 in the down slope of the triangular wave and a second comparator output 72 composed of a rectangular wave to fall at a prescribed value 82 in the up slope of the triangular wave 5 and to rise at a prescribed value 82 in the down slope of the triangular wave. Then, these first and second comparator outputs 71 and 72 are outputted as the rectangular wave outputs of two systems having a simultaneous off-period to alternately repeat on/off in the same cycle as the cycle of the triangular wave 5. |
