Abstract :
A prototype dual-mode voltage-controlled oscillator supporting two simultaneous oscillation modes is fabricated and demonstrated in a 0.18 mum CMOS process. The oscillator has two resonant ports while sharing one bias. Injection locking is applied to lock the low frequency, 4.8 GHz, to half of the high frequency, 9.6 GHz. The oscillator core consumes 7 mA from a 1.8 V supply. Measurement shows a tuning range of 5% and phase noise is -103 and -109 dBc/Hz measured at 1 MHz offset from the high and low frequency tones, respectively
