放大器
摘要：
本发明提供了放大器。一种放大器包括：信号处理电路，其生成与输入信号正交的正交信号；第一D/A变换器，其将正交信号变换成第一模拟信号；第二D/A变换器，其将所述输入信号变换成第二模拟信号；以及模拟计算电路，其基于来自所述第一D/A变换器的第一模拟信号和来自所述第二D/A变换器的第二模拟信号来生成恒包络信号。
摘要（英）：

An amplifier includes a signal processing circuit configured to generate an orthogonal signal orthogonal to an input signal; a first D/A converter configured to convert the orthogonal signal into a first analog signal; a second D/A converter configured to convert the input signal into a second analog signal; and an analog computing circuit configured to generate a constant envelope signal based on the first analog signal from the first D/A converter and the second analog signal from the second D/A converter.
