Abstract
Systems and methods provide analog delay elements, which may be utilized in isolation or in a cascade, such as for use within equalizers or other types of applications. For example, a delay element may include a broadband amplifier and a passive, programmable filter, which may provide a desired magnitude and group delay response over a wide frequency range while being tolerant of process variations. An equalizer, for example, may include the delay element within its feed forward filter and/or within its other circuits, such as within its adaptive coefficient generator or slicer input time-align circuit.
