For a lowcost solution, the most challenging blocks such as an RF transceiver, an RF power amplifier (RF-PA), and a high-power switching converter have to be integrated to eliminate the need for expensive multichip components. To support power scenarios of NB-IoT, low-power circuits and highly efficient power regulators are needed simultaneously [1]. This work aims for an all-in-one system to integrate all necessary blocks. An RF transceiver is integrated to support multiband cellular
