1. A clock transmission circuit comprising:
a voltage-to-current converter configured to convert a first clock into a first current;
a main transmission line configured to convey the first current into a second current;
a transformer comprising a primary inductor and a secondary inductor and configured to convert the second current received via the primary inductor into a second clock output via the secondary inductor;
a tuning capacitor configured to form a resonant network with the secondary inductor; and
a regenerative network connected to the resonant network and configured to provide a negative resistance to enhance resonance of the resonant network.
