Forward active bjt
WebThere are two types of basic transistor out there: bi-polar junction (BJT) and metal-oxide field-effect (MOSFET). In this tutorial we'll focus on the BJT, because it's slightly easier to understand. Digging even deeper into transistor types, there are actually two versions of the BJT: NPN and PNP. WebA transistor is often considered to be in saturation mode when the collector is higher than the base. But it still acts like forward active mode unless the voltage difference, V cb , is on the order of a diode drop (.6 V). If the base is at 1.3V and the collector is raised to about 1.86V or higher, the base current will go up and the collector ...
