摘要： Circuits that are matched to balanced codes may recover transmitted information in a noise resilient and power efficient manner. Circuit components for processing a balanced code may include one or more of: matched amplification of the signals representing the balanced code, matched equalization and/or filtering on the signals representing the balanced code, matched non-linear filtering on the signaling representing the balanced code to detect the presence of particular symbols and matched latching of the signals representing the balanced code. Such matched circuits and circuit components may be achieved at least in part by incorporating suitable common circuit nodes and/or a single energy source into circuit topologies.

摘要： Circuits providing low noise amplification with continuous time linear equalization are described. An exemplary circuit includes four amplification elements, such as MOS transistors. The amplification elements are arranged in differential pairs, and the differential pairs are cross-coupled with a frequency-dependent coupling, such as a capacitive coupling, to enhance high-frequency gain. The outputs of the amplification elements are combined to provide an output representing inverted and un-inverted sums of differences in the input signals.
