Abstract :
A new technique using left-handed resonator to generate multi-band mm-wave carrier signal is proposed in this paper. The left-handed resonator exhibits non-linear dispersion characteristic which enables uneven spacing between resonant frequencies. A dual band mm-wave oscillator in 90 nm CMOS technology is implemented to demonstrate this new technique. Using a mode selection switch, the proposed oscillator operates at 21.3 GHz and 55.3 GHz respectively with a total power consumption of 14 mW.
