Abstract :
A negative resistance approach decreases the loss of reflective-type passive phase shifters by as much as 5.9 dB over 2.27-2.45 GHz for use in multiple-antenna receivers. Conventional and low-loss prototypes each exhibit a phase-control range of -105° and consume 1.08 mm2 in 180 nm CMOS.
