precharge

Examples

• All

• A common clock simultaneously initiates precharge in all of the domino gates.

• The comparatively small number of transistors used in dynamic circuits reflects the fact that fewer transistors are needed to implement a function in dynamic circuits because the complementary p-FET network required for static circuits is replaced by a single precharge device in dynamic circuits.

• Staging the precharge signals allows foot devices to be eliminated, improving circuit performance by 5 to 15%.

  Academic text (2000)

• The precharge devices, PCHG(0:4), are added to precharge internal nodes and prevent charge sharing.

• SOI bipolar leakage from the precharge node to intermediate nodes can still occur.

  Academic text (2000)

• Therefore, internal nodes within the pulldown network of G4 are discharged during the precharge phase to reduce SOI bipolar effects.

• During the precharge, EA(14:4) and EAL(14:4) are low; during the evaluate phase, EA or EAL goes high for each bit.

  Academic text (2000)

• The half-latch or keeper p-FET transistor holds the dynamic node high and thereby the output low for conditions in which the precharge p-FET is off and there is no open path from the dynamic node to ground.

• In this example, the dual-rail outputs Ct and Cc are ORed to obtain a completion signal, which is inverted and delayed to drive the precharge signals for the domino levels that form the outputs B, C, and D.

• Before starting the device, ensure that the precharge occurs to prepare the necessary circuits.
