1. A multi-band equalizer for adjusting signal strength for a receiver receiving multi-band frequency signals, the multi-band equalizer comprising:
multiple resonators, each resonator having a first, second and third terminal, wherein each resonator comprises:
an inductor connected between the first and second terminals; and
two programmable capacitors connected in series between the first terminal and second terminal, the interconnection of the two programmable capacitors being tapped out and connected to the third terminal; and wherein
the multiple resonators are series connected such that the third terminal of a preceding resonator is connected to the first terminal of a succeeding resonator and, when used in the receiver, the first terminal of the first resonator is connected to a signal node of the receiver and the third terminal of the last resonator is connected to a signal ground, or the first terminal of the first resonator is connected to a signal ground and the third terminal of the last resonator is connected to a signal node of the receiver.
