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...

| description | 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 of a common source route with neutralisation technique and dual capacitive cross coupled‐common gate route to achieve high linearity and stability. In addition, it also includes dual negative resistance switches with improved inter‐stage matching network to enhance the conversion gain and to decrease the noise figure. The mixer achieves the conversion gain of 4.7 dB, the measured output 1‐dB compression point of 0.41 dBm and noise figure of 3.8 dB at 24 GHz. In an automotive radar application, the proposed mixer showed a high conversion gain, an excellent output 1‐dB and a low noise figure with power consumption of approximately 5.2 mW at a 1.2 V supply. |
