PURPOSE:To obtain a pulse signal without any phase difference with simple control constitution by connecting an output of each phase to ground or a power supply through a gate circuit controlled with an output of an opposite phase. CONSTITUTION:When outputs of inverters 4, 8 are as shown in solid lines A, B and the output of the inverter 4 rises, a gate element 11 is conductive and the output of an inverter 8 is descended forcibly as shown in broken lines. Moreover, even when the output of the inverter 4 is low, since the gate element 12 is energized by the output of the inverter 8, the output of the inverter 4 is kept to a high level as shown in broken lines and the level is kept to a low level by the leading of the output of the inverter 8. Thus, the start edge of the inverting pulse from the inverter 8 is made coincident with the start edge of the noninverting pulse from the inverter 4 and the end edge of the noninverting pulse of the inverter 4 is made coincident with the end edge of the inverting pulse from the inverter 8 to decrease the phase difference between the noninverting and inverting pulses. |
