Abstract

This paper presents a 24-GHz two-channel phased-array receiver. The receiver adopts the LO-phase-shifting approach and employs a sub-harmonically injection-locked phase-shifter. A CMOS-only prototype, fabricated in a 130-nm SiGe BiCMOS technology, draws 16-mA of current from a 1.5-V supply and consists of a injection-locked oscillator (operating as a phase-shifter, LO-buffer and frequency multiplier), a down-conversion mixer and an IF-buffer. The worst-case measured amplitude and phase errors are 1.5-dB and 4°. The two-channel receiver occupies an active area of 0.23-mm2.
