(mm-wave) bands requires a low-cost antenna module consisting of a phased-array transceiver with beamforming [1], an antenna array, and a power management IC (PMIC). Since a typical on-chip mm-wave CMOS power-amplifier (PA) arrays have poor power efficiency due to the lossy substrate and the low maximum available-gain frequency of CMOS processes, they cause serious thermal issues due to the high power density and reduce battery life in a mobile handset. Recently, supplymodulation (SM) techniques, such as an envelope tracking (ET) and an average-power tracking (APT) instead of a direct battery-connected supply, have been introduced to enhance PA efficiency [2]. However, these techniques have few challenges, such as limited ET tracking bandwidth and APT transition time,
