Abstract
The present disclosure relates to a 5G communication system or a 6G communication system for supporting higher data rates beyond a 4G communication system such as long term evolution (LTE). A low noise amplifier (LNA) in a wireless communication system according to an embodiment of the disclosure includes a first transistor and a first feedback transformer in which a gate of the first transistor is connected to a primary coil of the first feedback transformer and a source of the first transistor is connected to a secondary coil of the first feedback transformer. The first feedback transformer is configured to implement positive feedback to maintain an in-phase signal at the gate of the first transistor and the source of the first transistor.
