Patent attributes
A dynamic module and a decision feedback equalizer are provided. The decision feedback equalizer includes two dynamic modules, which have symmetric circuits and connections. The dynamic module includes a first domino circuit, a second domino circuit, and a storage circuit. In response to a first previous decision bit and a second previous decision bit, a first multiplexer output and a second multiplexer output are generated. The dynamic module alternatively operates in an evaluation period and a precharge period, depending on a clock signal. In the evaluation period, the first and the second multiplexer outputs are updated by the first domino circuit and the second domino circuit. In the precharge period, the first and the second multiplexer outputs are held by the storage circuit.
