放大器电路 Amplifier
（重定向自Class E amplifier）
放大器电路，或称放大电路，能增加信号的输出功率。它透过电源取得能量来源，以控制输出信号的波形与输入信号一致，但具有较大的振幅。依此来讲，放大器电路亦可视为可调节的输出电源，用来获得比输入信号更强的输出信号。
放大器的四种基本类型是电压放大器、电流放大器、互导放大器和互阻放大器。进一步的区别在于输出是否是输入的线性或非线性表示。放大器也可以通过在信号链中的物理位置来分类。

An amplifier, electronic amplifier or (informally) amp is an electronic device that can increase the power of a signal.
It does this by taking energy from a power supply and controlling the output to match the input signal shape but with a larger amplitude. In this sense, an amplifier modulates the output of the power supply to make the output signal stronger than the input signal. An amplifier is effectively the opposite of an attenuator: while an amplifier provides gain, an attenuator provides loss.
