Abstract: This paper proposes a hybrid resonant clocking distribution scheme.The global square-wave clock signal is produced and distributed by an improved rotary traveling wave oscillator.And the local resonant clock signal is generated by a transformer based resonant circuit.The hybrid clocking network with target frequency of 1.91GHz is designed and analyzed through SPICE under SMIC 0.13μm CMOS technology,which can reduced power consumption significantly in the clocking system.
