Low‐power CMOS voltage‐controlled oscillator with voltage‐controlled inductor for V‐band wireless personal area network communication systems

A low‐power voltage‐controlled oscillator (VCO) with voltage‐controlled inductor for V‐band wireless personal area network communication systems is presented in this study. The proposed VCO with a voltage‐controlled inductor provides a centre frequency of 45.62 GHz and was implemented in a 90 nm RF‐CMOS process. A tuning range of 1.28 GHz (44.98–46.26 GHz) with maximum control voltage of 1.0 V can be achieved. The phase noise is −92.8 dBc/Hz at 1 MHz offset frequency. The VCO core consumes 5.8 mW through a 1.0 V supply voltage and the active area is 0.13 mm 2 . The calculated figure‐of‐merit is −178.3.
