Product introduction

mosThe tube is metal (metal) -- oxide (oxide) -- semiconductor (semiconductorField-effect transistor, or metal-insulator (insulator) -- semiconductor.MOStubularsourceanddrainIt's interchangeable. They're both inPtypebackgatemesomorphicNType area. In most cases, the two regions are the same, and even if the two ends are switched, the performance of the device will not be affected. Such devices are considered to be symmetrical. A bipolar transistor amplifies a small change in current at the input and outputs a large change in current at the output. The gain of a bipolar transistor is defined as the ratio of output to input current (beta). Another type of transistor, called a field effect tube,FET) to convert a change in input voltage into a change in output current.FETThe gain of theta is equal to thistransconductance. Defined as the ratio of the change in output current to the change in input voltage.
