Thus, it forces the supply modulator (SM) to track the NR-100MHz envelope signal for power saving of an RF power amplifier (RF-PA) and requires a fast dynamic voltage-scaling (DVS) transition. For the 3G/LTE uplink, the SM has to satisfy low receiver-band noise (RxBN) for LTE-FDD bands [1] and a boosted output for Power Class 2 high-power user equipment (HPUE) in TD-LTE [2,3]. In order to support the 100MHz envelope tracking (ET) BW, the SM must have a 3dB bandwidth of at least 125MHz while keeping sufficient phase margin in the
