ABSTRACT:
A novel zero delay regenerative circuit is presented. The circuit, when connected to a data bus, suppresses noise, reduces time delay and provides sharper edge rates. A first input of a NOR gate is connected to an input node. A second input of the NOR gate is connected to the precharge clock of the bus. The output of the NOR gate is connected to the gate terminate of a field-effect transistor (FET). With the drain terminal connected to ground, the source terminal of the FET is connected to an output node. The input and output nodes are shorted together.
