Design of 1V CMOS 5.8 GHz VCO with Switched Capacitor Array Tuning for Intelligent Sensor Fusion
The article proposes wide tuning voltage-controlled oscillator (VCO) with adopting 4-bit switched capacitor array (SCA). The SCA with a cross-coupled switching pair, varactors and LC circuit at a low supply voltage of 1 V was fabricated in the 0.18-$\mu$ m 1P6M CMOS technology for intelligent sensor fusion. Measured results illustrate that at the voltage source of 1 V, the SCA VCO is tunable from 4.47 GHz to 5.95 GHz, corresponding to 28.7 %. The phase noise is -115.8dBc/Hz at 1 MHz offset from 5.8 GHz, the tuning range is 1880 MHz, the FOM is -182.7dBc/Hz, the power consumption is 7.0 mW and the chipset dimension is $0.817\times 0.599mm^{2}$
