Abstract:
A voltage controlled oscillator includes a first inductor, a second inductor, a first metal oxide semiconductor (MOS) transistor, a second MOS transistor, and an inductor-capacitor (LC) tank circuit. A first end of the first inductor and a first end of the second inductor are coupled to a first power rail. A drain node of the first MOS transistor is coupled to a second end of the first inductor. A drain node of the second MOS transistor is coupled to a second end of the second inductor. Source nodes of the first MOS transistor and the second MOS transistor are coupled to a second power rail. The LC tank circuit is coupled to gate nodes of the first MOS transistor and the second MOS transistor, wherein energy is magnetically pumped into the LC tank circuit through the first inductor and the second inductor.
