Design and Implementation of CMOS K-Band Phase Shifter using 90nm

We suggested designing a 24 GHz K band CMOS phase shifter using 90nm technology in this paper to satisfy the need for integrated and high-performance components for wireless system development. For the best phase shift and the least amount of insertion loss, the phase shifter operates between 18 and 27 GHz using a combination of lumped and distributed components. Important considerations are phase selectivity, linearity, and impedance matching. Theory and experiments demonstrate that it has a 180° range of phase shift and is utilized in high-frequency applications. The study demonstrates how 90nm CMOS technology can be used to improve wireless communication.
