Abstract

AbstractThis article presents a V‐band down‐converting cascode mixer fabricated in the 0.13‐μm CMOS process.The mixer utilizes the cascode topology and adds a buffer to avoid loading effects. The V‐band mixer exhibits a conversion gain of −1.7 dB, an input 1‐dB compression point of −8 dBm at RF of 60 GHz, IF of 5 GHz, and LO power of 0 dBm. The RF‐IF isolation is more than 26 dB. The LO‐RF isolation is more than 15 dB. In addition to the good agreement between simulation and measurement, the proposed cascode CMOS mixer with a small chip size has a complete measured performance for further 60‐GHz receiver RF front‐end integration. © 2010 Wiley Periodicals, Inc.
