A fully integrated CMOS 0 – 900 phase shifter in 0.18um TSMC technology is
presented. With the increasing use of wireless systems in GHz range, there is high
demand for integrated phase shifters in phased arrays and MIMO on chip systems.
Integrated phase shifters have quite a high number of integrated inductors which
consume a lot of area and introduce a huge amount of loss which make them impractical
for on chip applications. Also tuning the phase shift is another concern which seems
difficult with use of passive elements for integrated applications. This work is presents a
new method for implementing phase shifters using only active CMOS elements which
dramatically reduce the occupied area and make the tuning feasible.
Also a fully integrated millimeter-wave VCO is implemented using the same
technology. This VCO can be part of a 24 GHz frequency synthesizer for 24 GHz ISM
band transceivers. The 24 GHz ISM band is the unlicensed band and available for
commercial communication and automotive radar use, which is becoming attractive for
high bandwidth data rate.
