WebBJT. There are two types of MOSFET and they are named: N-type or P-type. BJT is of two types and they are named as: PNP and NPN. MOSFET is a voltage-controlled device. BJT is a current-controlled device. The input resistance of MOSFET is high. The input resistance of BJT is low. Used in high current applications. WebJan 28, 2024 · \$\begingroup\$ You can find a description of this role of the base current, among the others, on Streetman, "Solid State Electronic Devices", and in Levinshtein & Simin, "Transistors: from crystals to integrated circuit". Note: this does not imply that the BJT is exclusively current controlled, since as many other have said, voltage and current are …

WebMar 3, 2007 · Hence, the BJT is a current-controlled device. Specifically, the current through the device (collector to emitter -- assuming an NPN) is a function of the current into the base. And, since you have current flow through the device and some Vce, like the FET's drain to source, you have a resistance, collector to emitter. ... WebMar 6, 2015 · Hence, the BJT cannot be used as avoltage-controlled resistor. However the situation is completely different for FET´s in particular for JFET´s. These devices have another working principle than BJT`s - they can be seen as voltage controlled resistors within the so-called "linear" region (ohmic region) for rather small VDC values (up to 1V). d6 arrowhead\u0027s
