Abstract :
An analysis of reflective-type phase shifters with transformed single-resonant loads is presented. Several components of the standard lumped-element coupler can be eliminated without significant performance degradation, to allow more compact implementations. A reflective-type phase shifter operating at 2.0 GHz has been designed in a 0.18 mum CMOS process, occupying an area of 0.75 mm2 and consuming 5.4 mW of power. Simulations have been performed on the extracted circuit, including all resistive and capacitive parasitics. The phase shift range is 338deg for a control voltage range from 0-1.8 V, and 675deg for 0-2.5 V. The maximum loss and noise figure are -10 dB and 19 dB, respectively, over the control voltage range from 0-1.8 V
