Abstract:
Data latch circuit and method of low power decision feedback equalization (DFE) system is disclosed. In one embodiment, the data latch circuit of the of a decision feedback equalization (DFE) system includes a first parallel n-channel metal-oxide-semiconductor field-effect transistor (NMOS) pair to input a differential input voltage. The data latch circuit also includes a second parallel NMOS pair coupled to the first parallel NMOS pair to input a decision feedback equalization (DFE) voltage. The data latch circuit further includes a cross-coupled PMOS pair to generate a positive feedback to the first parallel NMOS pair and/or the second parallel NMOS pair. In addition, the data latch circuit includes a cross-coupled NMOS pair to escalate the positive feedback. Furthermore the data latch circuit includes a latching circuit to generate a signal data based on the sinking of a current at an input of the latching circuit and/or the positive feedback.
