ABSTRACT:
A first circuit and a second circuit are connected by a pumped signal line that conducts a signal having a plurality of states. A dynamic termination circuit is connected to the pumped signal line. The dynamic termination circuit includes a switch responsive to the signal conducted by the pumped signal line such that the dynamic termination circuit is enabled only in response to certain of the plurality of states of the signal. In one embodiment, the switch is a first transistor that is coupled in series with a first impedance between a first reference voltage and an intermediate node. In this embodiment, the dynamic termination circuit further includes a second transistor coupled in series with a second impedance between a second reference voltage and the intermediate node and only first and second inverters that are each coupled between the intermediate node and the control input of a respective one of the first transistor and the second transistor.
