Semiconductor integrated circuit, phase-locked loop, radar and electronic device

Abstract

A semiconductor integrated circuit, a phase-locked loop, a radar sensor and an electronic device. The semiconductor integrated circuit comprises a substrate layer, and a plurality of insulated metal layers arranged on the substrate layer, wherein the plurality of metal layers comprise a shielding structure layer, a first device structure layer and a plurality of second device structure layers. The semiconductor integrated circuit contains an oscillator for outputting differential signals, and contains: a first inductor and a second inductor formed in different second device structure layers; a capacitor device formed in the first device structure layer; and a first transistor and a second transistor formed in the substrate layer, wherein the first inductor and the second inductor are symmetric about the same axis of symmetry, and the shielding structure layer is provided with a shielding structure for shielding interference signals leaked by the first inductor and/or the second inductor.
