Abstract:
1. An apparatus comprising: a first pseudo-inverter including a first input node, a second input node, and an output node, the first pseudo-inverter adapted to generate output information at the output node based on information coupled to the first and second input nodes; a feedback circuit to generate feedback information based on at least the output information, wherein, the feedback circuit includes a second pseudo-inverter having a first input node coupled to the output node of the first pseudo-inverter, a second input node coupled to one of the first and second input nodes of the first pseudo-inverter, and an output node to provide a first copy of the feedback information to the select circuit; and a select circuit coupled to receive input information and the feedback information and to selectively transfer the input information and the feedback information to the first and second input nodes.
