Abstract

A flip-flop of a master-slave type of a CMOS structure having no P channel transistor between nodes of the master flip-flop and of the slave flip-flop is provided. Only one P channel MOS transistor is existent in a route of the current controlling a rise time and a trail time of output signals, so that it is possible to function at a high speed.
