Performance Enhancement of CMOS VLSI Circuits by Transistor Reordering

A method which uses transistor reordering for the performance enhancement of CMOS circuits is presented. The proposed technique achieves significant reduction in propagation delays with little effect on layout area. The technique can be coupled with transistor sizing to achieve unbounded improvement in circuit delay, and it can be used to decrease dynamic power dissipation. In particular, excellent results have been achieved when the method is applied to data path circuits.
