Abstract:
1. A voltage-controlled oscillator comprising: a first voltage node to receive a first voltage; a second voltage node to receive a second voltage; a third voltage node to receive a third voltage; an active-circuit arrangement facilitating generation of a first oscillating signal at a first output node and a second oscillating signal at a second output node, the active-circuit arrangement comprising: a resonator arrangement coupled to the first voltage node and the second voltage node to influence an oscillation frequency for the first oscillating signal and the second oscillating signal based on a difference between the first voltage and the second voltage, the resonator arrangement including a first inductive element coupled between the second voltage node and a first node and a second inductive element coupled between the second voltage node and a second node; a first capacitive element configured electrically in series between the first output node and the resonator arrangement; a second capacitive element configured electrically in series between the second output node and the resonator arrangement; a third inductive element connected between the first output node and the third voltage node; and a fourth inductive element connected between the second output node and the third voltage node, wherein:
