A 24-GHz 90-nm CMOS beamforming receiver front-end with analog baseband phase rotation

Axholt, Andreas LU and Sjöland, Henrik LU (2010) European Solid-State Circuits Conference (ESSCIRC), 2010
Abstract
A 24 GHz 2-path beamforming receiver front-end

in 90 nm CMOS is presented. It consists of two direct conversion

front-ends followed by a baseband block performing phase

rotation and signal combination. The baseband phase rotation

is performed by combining the quadrature phases using digitally

controlled weights, achieving a phase resolution of 11 degrees.

From each of the two inputs the front-end measures; a conversion

gain of 13 dB, NF < 9 dB, ICP1db = -20.5dBm, IIP3 = -7.5dBm,

LO-RF isolation 48dB, all at a power consumption of 33.6mW

from a 1.2 V supply. The chip area is 1400x850 μm2, including

pads, of which the phase rotation block occupies... (More)
