A decoupling technique for CMOS strong-coupled structures

A novel decoupling technique for CMOS gate with strong-coupled components is presented. The feedback structure is reduced to a unidirectional one, which facilitates the fast-timing simulation. Based on the waveform relaxation technique, the decoupling principles and procedures are discussed in detail. Most of the factors, which influence the operation of the strong-coupled components, are taken into account. The proposed method is validated by SPICE simulation.
