Title: Semiconductor integrated circuit
Inventor: SAWANO TOMONORI
IPC: H03K19/096
Filed: 1999-05-18
Abstract: PROBLEM TO BE SOLVED: To prevent malfunction due to deviation between inverted clocks and to improve the reliability by providing a correcting domino circuit between domino circuit groups of a front and a rear stages and holding the generation output of the front stage until the decision period of the rear stage starts. SOLUTION: A domino circuit train 4 is constituted by providing a correcting domino circuit 4c between a domino circuit groups 4a and 4b cascaded to latches 1 and 2 respectively and the signal from a latch 12 is decided by the domino circuit group 4a from the rise of a clock ϕ1, processed by the domino circuit group 4b in synchronism with the rise of the phase-inverted clock ϕ2 of the ϕ1, and stored in a latch 23. When the output of the latch 2 is 1, the circuit group 4a outputs 1 through the rise of the ϕ1 and the ϕ2 falls, so that the circuit group 4b outputs 0. Nearly when the ϕ1 falls and the circuit group 4a begins to be precharged, the ϕ2 rises and the circuit group 4b starts decision operation. The correcting domino circuit 4c holds a decision value even if the output of the circuit group 4a becomes 0 until the ϕ2 rises.
