A high-frequency, low-voltage, low-power tunable oscillator using active inductors as resonators is designed and simulated in TSMC 0.20-μm CMOS technology. The oscillation frequency of the small and compact transistor-only circuit is 4.95 GHz with THD≈-80 dB. Phase noise is approximately -81 dBc/Hz at 500-kHz offset. For a 1.8-V supply voltage, the power consumption is less than 1.16 mW.
