11. An integrated circuit configuration for selectively filtering unwanted frequencies from a signal path of a frequency-based circuit, including:
a) a frequency-based circuit having a common signal path;
b) at least one tunable filter coupled to the common signal path of the frequency-based circuit, for selectively filtering unwanted frequencies from the common signal path of the frequency-based circuit; and
c) at least one bypassable compensation capacitor circuit, each coupled in parallel with a corresponding tunable filter and configured to match and substitute for an effective capacitance of such tunable filter when such tunable filter is not activated;
wherein the frequency-based circuit and each tunable filter are co-designed to absorb and compensate for residual and other parasitic impedances present in the integrated circuit configuration.
