Abstract

A high input power range phase shifter is designed and fabricated on 0.18-μm CMOS technology. With proposed variable gain amplifier in I/Q vector combination based phase shifter, the performance of output signal has been improved. From measured results, the gain variation and phase distortion versus input power of output signal are smaller than 1.5 dB and ±2°, respectively. The minimum DC consumption of core circuit is 15.46 mW from 1.8 V supply voltage.
