Abstract

This application relates to the field of electronic device technologies, and discloses a multi-mode inductive circuit, a control method, a low noise amplifier, and an electronic device. The multi-mode inductive circuit includes an input node, at least two inductors, at least three switches, and an output node. The input node is electrically connected to a first terminal of one of the inductors. The input node is further electrically connected to a first terminal of the other inductor through a switch. A second terminal of the one inductor is electrically connected to the output node through an other switch. The second terminal of the one inductor is further electrically connected to the first terminal of the other inductor through the other switch. A second terminal of the other inductor is electrically connected to the output node. At least four inductance values of the multi-mode inductive circuit are determined through closing and opening of the at least three switches. Based on the solution of this application, inductance values for more modes may be obtained, thereby obtaining more gain modes for the low noise amplifier, and the circuit structure is simple.
