A voltage controlled oscillator (VCO) may include a stack of a plurality of non-connected inductors that are magnetically and/or electrically through capacitor (AC) coupled to each other and not directly physically connected to each other. The plurality of inductors includes a first inductor connected to a supply voltage and a second inductor connected to a VCO control voltage. The VCO may include a first varactor having a gate coupled to a first terminal of the second inductor to receive the VCO control voltage, a second varactor having a gate coupled to a second terminal of the second inductor to receive the VCO control voltage, and an oscillator sub-circuit coupled to first and second terminals of the first inductor. In one example implementation, the second inductor may contribute to the overall inductance of the inductor stack and provide AC decoupling and/or DC coupling between the VCO control voltage and the varactor(s). |
