Patent ID: 8686805

Claim:
An oscillator for use in generating frequencies in a frequency synthesizer, said oscillator comprising: a first inductor element forming a metal trace loop with at least one turn; a first capacitive circuit arranged to form a first resonance circuit with the first inductor element and being connected to the first inductor element through at least one first connection terminal, wherein the first capacitive circuit comprises at least one capacitive element and an electrical components arrangement configured to establish and maintain an oscillation; a second capacitive circuit comprising at least one capacitive element and an arrangement of electrical components, said second capacitive circuit configured to form a second resonance circuit with the first inductor element and connected to the first inductor element through at least one second connection terminal located on the opposite side of the first inductor element with respect to the first connection terminal of the first capacitive circuit; and wherein the first and second resonance circuits are tuned to substantially the same frequency.
