    This paper introduces an automatic amplitude control (AAC) mechanism implemented on a class-C LC-based phase shifter. The AAC technique compensates for the amplitude attenuation of the phase shifter as a function of frequency and provides output swing control that enhances the suitability as a phase shifter in the auxiliary path of a load-modulated balanced power amplifier (LMB-PA). It can be utilized to calibrate and fine-tune the power amplifier (PA) performance after fabrication to achieve optimal performance. The circuit is designed and laid out using 22−nm FD-SOI process technology. To demonstrate the proposed idea, the frequency of operation was chosen as 2.4 GHz. The total power consumption varies between 0.52 − 1 mW due to phase control from 0 − 120â—¦ with 0.085 dB amplitude error.
