STATIC FLIP-FLOP CIRCUIT

摘要

In a master circuit (1) and a slave circuit (2), the size of the transistor constituting a data holding differential pair is set smaller than the size of the transistor constituting a data read out differential pair. Furthermore, a flip-flop circuit is operated in such a high operation speed range that the current of the data holding differential pair becomes smaller than the current of the data read out differential pair and the current of the data holding differential pair becomes not greater than the allowable current of the transistor constituting the data holding differential pair.
