SEMICONDUCTOR INTEGRATED CIRCUIT AND METHOD FOR DESIGNING ITS ARRANGEMENT

摘要

PROBLEM TO BE SOLVED: To prevent any possibility that a racing period is generated in a circuit in which the spacing period of two-phase clock signals is necessary. SOLUTION: This semiconductor integrated circuit is provided with a clock signal source for outputting two-phase clock signalsϕ1 andϕ0 having a spacing period, two-phase clock wiring 11 and 12 far transmitting the two-phase clock signals supplied from the clock signal source to latch circuits 15 and 16, and a waveform correction circuit 17 having plural NMOS transistors N1 and N2 connected between the two-phase clock wiring and a GND node for securing the spacing period of the two-phase clock signals.
