Continuous Active Phase Shifter Design and Analysis for Millimeter-Wave Circuits

This brief presents a continuous active phase shifter for millimeter-wave phased-array transceivers. Having an all-pass network frequency response, the proposed phase shifter provides continuous insertion phase control and nearly constant insertion loss regardless of the insertion phase variation. A complete analysis for the phase shifter is provided along with circuit measurement results. The phase shifter is fabricated in a 0.13-μm commercial CMOS technology. A phase tuning range larger than 90 ° and -7 dB of insertion loss are achieved for the phase shifter.
