A 60-GHz Wideband Down-conversion Mixer for Low-power and High-speed Wireless Communication

Abstract

This paper presents a high-speed and low-power down-conversion mixer implemented 65 nm CMOS technology. The proposed mixer operates at 60-GHz carrier frequency. The mixer consists of a double-balanced gilbert cell and current-bleeding transistors. The mixer consumes 20 mW with the buffer but 8 mW without the buffer and achieves a conversion gain of - 1.2 dB and IF bandwidth of 8 GHz at 60-GHz carrier frequency. As a result, this low-power and wideband mixer can demodulate a Gbps-modulated signal.
