Abstract
PURPOSE: To prevent the generating of spiky current, by limiting the dimension of current flowing through a transistor only for a period necessary for the change- over when turning the transistor ON-OFF.
CONSTITUTION: When this circuit is arranged by NAND circuits ND1, ND2 and ϕ signals are changed over to a low level from a high level or inversely changed over, the output of each NAND circuit is on a high level during the applying period of the gate pulse and transistors Q2, Q3 are also under OFF conditions by applying gate pulse signals on low levels with wider width than the widest width by the dispersion of the charge storage time ta of each transistor to the input sides of the one sides of each NAND circuit. Thus, the generation of spiky current can be prevented.
