A high‐linearity high‐gain up‐conversion mixer for 24 GHz automotive radar applications

Abstract This paper presents a high conversion gain and highly linearised up‐conversion mixer designed in 65 nm CMOS process, which translates intermediate frequency of 2.4 GHz and local oscillator frequency of 21.6–24 GHz in radio frequency. In the proposed mixer, the tranconductance stage consists...
