Abstract:
Methods and systems for a configurable finite impulse response (FIR) filter using a transmission line as a delay line are disclosed and may include selectively coupling one or more taps of a multi-tap transmission line to configure delays for one or more finite impulse response (FIR) filters to enable transmission and/or reception of signals. The delays may be configured based on a location of the one or more selectively coupled taps on the multi-tap transmission line. The FIR filters, which may include one or more stages, may be impedance matched to the selectively coupled taps. The multi-tap transmission line may be integrated on the chip, or a package to which the chip is coupled. The multi-tap transmission line may include a microstrip structure or a coplanar waveguide structure, and may include ferromagnetic material. The distortion of signals in the chip may be compensated utilizing the FIR filters.
