    Abstract: A novel and useful linear, efficient, smart wideband CMOS hybrid power amplifier that combined an analog linear amplification path and a digital power amplification (DPA) path. PA path control logic analyzes the input I and Q signals and determines which amplification paths to steer the input I and Q signals to. The analog linear amplification path comprises digital to analog converters for both I and Q paths and one or more analog linear power amplifiers. The digital power amplification path comprises I and Q up-sampling circuits and I and Q RF DAC circuits (e.g., digital PA circuits). In operation, the PA path control logic compares the I and Q signals to thresholds (which may or may not be different) and based on the comparisons, selects one or more paths for the input I and Q signals. Whether the signals from the analog and digital amplification paths are to be combined or selected (i.e. switched), the PA path control circuit is operative to generate select (switch) control signals which are applied to summer/selector elements which generate the output of the hybrid PA.

    Abstract translation: 一种新颖有用的线性，高效智能宽带CMOS混合功率放大器，其组合了模拟线性放大路径和数字功率放大（DPA）路径。 PA路径控制逻辑分析输入I和Q信号，并确定哪些放大路径将输入I和Q信号转向。 模拟线性放大路径包括用于I和Q路径的数模转换器和一个或多个模拟线性功率放大器。 数字功率放大路径包括I和Q上采样电路以及I和Q RF DAC电路（例如，数字PA电路）。 在操作中，PA路径控制逻辑将I和Q信号与阈值进行比较（其可能或可能不同），并且基于比较，为输入I和Q信号选择一个或多个路径。 来自模拟和数字放大路径的信号是否被组合或选择（即切换），PA路径控制电路可操作地产生选择（开关）控制信号，其被施加到加法器/选择器元件，其产生 混合PA。
