A single-element of ka-band 0.13µm CMOS all-RF phased-array receiver with 4-bit phase resolution

摘要

A single-element of phased-array receiver front-end has been developed in 0.13μm CMOS for 26-29GHz application. This design uses the All-RF architecture with LNA and phase shifter blocks to achieve lowest NF, rms gain error and rms phase error. The 26-29GHz single-element achieves a post-simulation result NF of 6.5dB, rms gain error of 1.9dB, rms phase error of 7.5 degree at 27.5 GHz. The whole circuit dissipates 35mW from 1.8-V supply.
