Abstract (in Japanese) (See Japanese page) 
(in English) A quasi-millimeter CMOS phase shifter which employed a vector sum structure is designed. It consists of an active balun, LC high pass filters, and a vector summer to achieve 360 degree phase control. To operate with small phase resolutions, we propose a novel vector summer to reduce leakages of undesired vector signals. It uses four shunt transistors and two cancellation transistors, and the effectiveness is demonstrated by a calculation using 0.18um CMOS device models. The fabricated CMOS vector-sum phase shifter achieves 360 degree phase control within 1.5 degree step.
