A 95GHz Receiver with Fundamental-Frequency VCO and Static Frequency Divider in 65nm Digital CMOS

Abstract

This paper presents a fully integrated receiver, with LNA, mixer, IF amplifier, fundamental-frequency quadrature VCO, and static frequency divider, operating at 95GHz in a 65nm general-purpose (GP) CMOS technology. The receiver consumes 206mW from a 1.2V/1.5V supply. With large RF and IF bandwidths of over 19GHz and 16GHz, respectively, it is suitable for passive-imaging applications, and for wireless chip-to-chip communication at data-rates exceeding 20Gb/s. Together with the recently reported 60GHz receiver in 90nm CMOS, this 95GHz receiver in 65nm CMOS demonstrates that scaling of entire mm-wave receivers is possible in both frequency coverage and across technology nodes.
