An Inductorless 60GHz Down-Conversion Mixer in 22nm FD-SOI CMOS Technology

This paper presents an inductorless 60GHz down-conversion mixer integrated in a 22nm FD-SOI CMOS technology. The mixer is based on a single-balanced architecture followed by a common-source output buffer, and it performs a zero-IF conversion with –3dB corner frequency at 1GHz. The maximum differential single-side-band (SSB) conversion gain is 6dB, in agreement with simulation and circuit analysis. The required LO power is –4dBm, while the dissipated power is 18mW. The silicon footprint is 0.05mm2, which to the knowledge of the authors is the smallest reported so far for down-conversion mixers operating at 60GHz, with a factor 3 of improvement.
