Web2.4.1 Pushing Bubbles. The AOI and OAI logic cells can be built using a single stage in CMOS using series–parallel networks of transistors called stacks. ... There is a branch of full-custom VLSI design that uses pass-transistor logic. Much of this is based on relay-based logic, since a single transistor switch looks like a relay contact. ... WebRetiming is the technique of moving the structural location of latches or registers in a digital circuit to improve its performance, area, and/or power characteristics in such a way that preserves its functional behavior at its outputs. Retiming was first described by Charles E. Leiserson and James B. Saxe in 1983. [1]
