1. A wide-bandwidth resonant circuit comprising:
a first node and a second node;
a positive resonant circuit coupled between the first node and the second node, the positive resonant circuit is configured to resonate at a resonance frequency to present a respective lower impedance between the first node and the second node below the resonance frequency; and
a negative resonant circuit coupled between the first node and the second node and in parallel to the positive resonant circuit, the negative resonant circuit is configured to resonate at the resonance frequency to present a respective lower impedance between the first node and the second node above the resonance frequency.
