Estimating the term…
An apparatus and method for a frequency based integrated circuit that selectively filters out unwanted bands or regions of interfering frequencies utilizing one or more tunable notch or bandpass filters or tunable low or high pass filters capable of operating across multiple frequencies and multiple bands in noisy RF environments. The tunable filters are fabricated within the same integrated circuit package as the associated frequency based circuitry, thus minimizing R, L, and C parasitic values, and also allowing residual and other parasitic impedance in the associated circuitry and IC package to be absorbed and compensated.
An integrated circuit configuration including:
An integrated circuit including:
A method for selectively filtering unwanted frequencies from a signal path of a frequency based integrated circuit, including:
A radio frequency (RF) circuit having a shared tunable filter, including:
A wide-band tunable radio frequency (RF) filter, including at least one of an electrically-tunable capacitor or electrically-tunable inductor having sufficient variability in corresponding capacitance or inductance to enable a wide range of variability in the cut-off frequency of the wide-band tunable RF filter and configured to be connected such that the single wide-band tunable RF filter provides filtering of multiple RF signal bands by filtering unwanted frequencies from a selected RF signal path corresponding to an RF circuit with respect to an operational RF frequency band of such RF circuit.
The RF circuit of claim 48, wherein the wide-band tunable RF filter is one of a tunable notch filter or a tunable bandpass filter.
A tunable capacitor compensated filter, including:
