A method and circuit for implementing a broadband resonator for resonant clock distribution, and a design structure on which the subject circuit resides are provided. The circuit includes a pair of first inductors, and a second inductor and a capacitor coupled between a respective first end of the respective first inductors. An opposite free end of the respective first inductors is connected to a respective clock transmission line and connected in parallel to a load capacitance. A frequency response of the circuit includes two poles and a zero in a frequency band of the resonant clock distribution system.
