Semiconductor integrated circuit

Abstract

Abstract PURPOSE:To stabilize the level of a dynamic node and to stabilize a domino circuit by providing a PMOS transistor supplying the HIGH level to the dynamic node. CONSTITUTION:The semiconductor integrated circuit forming the domino circuit is provided with a first PMOS transistor 1 where a source is connected to a prescribed NMOS circuit network 4, the NMOS circuit network 4 where gates are mutually and continuously connected to first and second signal input terminals 51 and 52, a third NMOS transistor where the gate is connected to a control signal input terminal 53 and a drain is connected to the source of the second NMOS transistor as well as the source is connected to an earth point, a second PMOS transistor 6 where the drain is connected to the power supply on a high potential side and the source is connected to the source of the first PMOS transistor 1, and the gate is connected to a signal output terminal 54, and an inverter 7 where the input side is connected to the source of the second PMOS transistor and the output side is connected to the signal output terminal 54.
