Abstract

This paper presents a compact wideband amplifier at 160 GHz in 40-nm CMOS. Typical wideband amplifier design requires higher-order matching networks and more gain stages, both of which demand larger die area. The presented 8-stage amplifier uses a compact 'fishbone' layout technique, and its core size is as small as 190 × 123 μm 2 . A small-signal gain of 15 dB at 160 GHz and a 3-dB bandwidth of 41 GHz are achieved. It consumes 117 mW from a 0.9 V voltage supply.
