摘要：
The following discussion presents a novel technique of power management in TX 4G transmit path, capable of efficiently handling wide channel bandwidth and high peak-to-average-power-ratio (PAPR). It consists in a power adaptive closed loop, based on a switched multi-cell power amplifier (PA) core and a novel Delta-Sigma control loop topology. This work was carried out with a ST Microelectronics SiGe technology.
