Abstract
Methods and apparatus are provided for programmable active inductance. The disclosed active inductor devices provide a tunable bandwidth with improved linearity. The disclosed active inductors have a variable frequency response corresponding to a variable inductance of the active inductor. The active inductor comprises a variable resistive circuit having an effective resistance, wherein the variable resistive circuit is comprised of at least one resistor that can be selectively bypassed in the variable resistive circuit to vary the effective resistive. The active inductor has an inductance that can be varied by varying the effective resistance.
