Abstract:
Various embodiments are described herein for an asymmetrical bus keeper circuit that provides asymmetrical drive towards one logic level. The asymmetrical bus keeper circuit comprises a first inverter stage having an input node and an output node, an asymmetrical inverter stage having an input node and an output node and a feedback stage with an input node and an output node. The input node of the asymmetrical inverter stage is connected to the output node of the first inverter stage. The input node of the feedback stage connected to the output node of the asymmetrical inverter stage and the output node of the feedback stage connected to the input node of the first inverter stage. The asymmetrical stage provides asymmetrical drive towards one logic level.
