Zusammenfassung:	Certain aspects provide a circuit for generating an oscillating signal. The circuit generally includes a voltage-controlled oscillator (VCO) having cross-coupled transistors, a first capacitive element and a second capacitive element coupled to the cross-coupled transistors, and a first inductive element and a second inductive element coupled to the cross-coupled transistors. First terminals of the first inductive element and the second inductive element are coupled to first terminals of the first capacitive element and the second capacitive element, respectively. The circuit also includes a control circuit having an output coupled to a supply voltage node at second terminals of the first inductive element and the second inductive element, and a feedback path coupled between the VCO and an input of the control circuit.
