摘要

图腾柱B类包络跟踪电源调制器一般由两个反相工作的单端晶体管组成。在本文中，图腾柱B类电源调制器设计由两个变压器组成，用于分割输入信号和合并输出信号。图腾柱由两个连接的n通道bjt组成，其中输出被带到第二个变压器。结果表明，所设计的电源调制器能够在100MHz ~ 1ghz的宽带宽范围内工作。该电源调制器作为混合电源调制器，在变压器处将直流信号与高频信号相结合。

High Bandwidth Hybrid Supply Modulation Using Totem Pole Configuration for Envelope Tracking Applications

Totem pole class B envelope tracking supply modulator is generally consisting of two single ended transistors operating in anti-phase. In this paper, the totem pole class B supply modulator design consists of two transformers that are used to split the input signal and to combine the output signal. The totem pole consists of two N-channel BJTs connected where the output is taken to the second transformer. The result shows that the designed supply modulator is able to operate in wide bandwidth from 100MHz to 1 GHz. This supply modulator works as hybrid supply modulator which the DC signal will be combined with the high frequency signal at the transformer.
