Abstract

A 5-bit active vector-sum phase shifter operated in 0.75-2.67 GHz is implemented in 0.18-μm CMOS technology. A tunable RC quadrature all-pass filter and a resistor-string VGA are proposed for quadrature phase generation and magnitude ratio tuning, respectively. The chip size is 0.89 mm². The DC power consumption of core circuit is 6.39 mW from 1.8 V supply. The RMS magnitude error and RMS phase error are below 0.74 dB and 7.2 degrees.
