This manuscript details our latest 90nm CMOS W-band receiver design where the RF LNA, resistive mixer, IF differential amplifier and LO tripler have been integrated, thus allows the whole 77-110GHz spectrum to be down-converted into quasi-DC -33GHz using a much lower microwave frequency. In addition to being used in our broadband receiver array project, this W-band circuit is also eligible for the conventional 77/94GHz vehicular and surveillance applications. This 90nm-CMOS receiver with LO tripler has around -0.4dB conversion gain, 18dB noise figure, 48dB LO-IF isolation, and its chip size is 950-times-750μm2, with 114mW power dissipation at 1.3V DC bias. |
