PURPOSE:To prevent malfunction of a logic circuit caused by overlap of a polyphase clock by using a detection signal from a detection circuit so as to correct a waveform of the polyphase clock. CONSTITUTION:A circuit 1 detecting overlap of high level of biphase clocks CLK1, CLK2 consists of inverters 3-9 and NOR gates 6,10,11. Then a detection signal outputted from the detection circuit is used to eliminate the overlapped high level of the biphase clock at a circuit 2, which consists of NAND gates 12,14 and inverters 13,15. |
