The first transformer includes first and second inductively coupled inductors. The second transformer includes third and fourth inductively coupled inductors. Each inductor includes multiple first segments in a first metal layer; multiple second segments in a second metal layer; first and second inputs, and multiple through vias coupling the first and second segments to form a continuous path between the first and second inputs. The first input of the first inductor is coupled to an amplifier input; the first input of the second inductor is coupled to the first transistor gate; the first input of the third inductor is coupled to the first transistor drain, the first input of the fourth inductor is coupled to an amplifier output. The second inductor inputs and the first transistor source are coupled to ground."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Three dimensional inductor, transformer and radio frequency amplifier","description":"A three dimensional on-chip radio frequency amplifier is disclosed that includes first and second transformers and a first transistor.
