This paper presents a 4-channel ultra-wideband (UWB) timed array beamforming receiver designed in a standard 0.18-$\mu$m CMOS technology. The proposed timed array receiver achieves a maximum delay of 250 ps at the maximum beam steering angle of $\pm$42$^{o}$ with 10.5$^{o}$ (8 steps) steering resolution and 2-cm antenna spacing. Each receiver channel provides gains ranging from 3.6 to $-$35 dB and less than 8\% delay variation for all delay settings over a 3.1$-$10.6-GHz frequency range, while consuming a maximum of 58 mW power from a 1.8-V supply. The average $-$1-dB compression point $\textrm{P}_{\textrm{1dB}}$ is $-$9.9 dBm. The proposed architecture is modeled and simulated by using Virtuoso Cadence.
