    電晶體就是transistor

    我以前寫過一篇此產業及產品的研究報告

    不過是英文的,節錄於下給你參考,看了之後就會很清楚了:

    關於transistor電晶體基本敘述:

    Transistors are semiconductors that amplify and switch analog signals, radio frequency signals, and power. MOSFET is used to switch and manage power so that a minimal amount of energy is wasted as power passes through an electronic device. Common applications include mobile phones, notebook computers, communication networks, and electronics for automobiles.

    關於這類分離式元件產品特性:

    Discrete semiconductors differ from passive components because they require power to function, as opposed to passive components which simply store, regulate, and restrict electrical current. Discrete semiconductors derive their name from the fact they generally perform one simple function. They perform power conversion functions in electronic equipment, converting, amplifying, switching, and routing electrical energy and signals in circuits. Discrete semiconductors convert electrical power into efficient, usable power in four stages: (1) input rectification, (2) control, (3) switching, and (4) output rectification. Input rectification converts alternating current (AC) to direct current (DC). The control function measures incoming electricity and sends a signal to a switch. The switch sends regular pulses of energy that can be handled more efficiently in small increments. And finally output rectification reconfigures the elements into a form usable by electrically operated equipment. This may be something similar to power line conditioning, whereby the current is smoothed via buffering at the silicon chip; in the case of a diode, the current is allowed to traverse the circuit in one direction, but is prohibited from moving back across the circuit in the other direction.
