共射极放大器（Common Emitter Amplifier）是最常用的放大器类型之一，因为它能提供极高的电压增益。甲类共射极放大器的设计目标，是从仅有几毫伏的输入信号中产生较大的输出电压摆幅，因此这种电路主要被用作“小信号放大器（Small Signal Amplifier）”。 然而 ...

If you have read an amplifier review or looked at the specifications for an amp, the chances are that you have come across a term such as 'Class A/B'. In fact, this is just one of a number of ...

A Class D audio amplifier is basically a switching amplifier or PWM amplifier. There are a number of different classes of amplifiers. We will take a look at the definitions for the main ...

Different classes of amplifiers. What are the benefits of class AB amplifiers? Patents that address the quiescent current of class AB amps. Amplifiers have many ...

If you know anything about a transistor, it’s probably that it’s a three terminal device whose output pin forms part of a potential divider whose state is dependent on what is presented to its input ...

Just today I read on an internet forum a post by a "hot" new manufacturer of class D amplifiers saying that "the only way to solve the interference problem is to put the amplifier in a completely ...

With so much attention on IBOC, it is appropriate to step back and review the basic principles of RF amplifiers. The radio transmitter is a collection of stages. Each stage modifies the signal in some ...

Most audiophiles and enthusiasts have grown up with at least a basic understanding of what an amplifier does. It takes a tiny alternating electrical signal that represents the moment-to-moment ...

When people think of the Yamaha brand, they likely think of one of two companies. There's the Yamaha Motor Company, which is responsible for various modes of transportation, including some powerful, ...
