概要

論文の詳細を見る
A fully integrated broadband up-conversion mixer with low power consumption is demonstrated on 90nm CMOS technology in this paper. This mixer has a single-ended input and a multi-layer stacked Marchand balun is used for converting the differential output of the single-balanced mixer topology to a single-ended output. This balun employs inductive coupling between two metal layers and includes slotted shields to reduce substrate losses. The circuit size is 650μm×570μm. At 22.1GHz, the integrated mixer achieves a conversion gain of 2dB with a maximum power dissipation of only 11.1mW from a 1.2V dc power supply at LO power of 5dBm. Input referred 1-dB compression point is -14.8dBm. The LO and RF return loss are better than 10dB for frequencies between 20-26GHz.
