http://www.sophphx.caltech.edu/Physics_5/Experiment_6.pdf WebFor switching applications, the BJT is most like a closed switch when it is in the saturation region, where VCE is small. It is most like an open switch when it is in cutoff, with iC = 0. A BJT is often used as a current ... In circuit simulation, this is done using a DC voltage sweep analysis. The result is a voltage transfer curve (VTC). ...

WebThe BJT is "cutoff" because IC is essentially zero and all of VCC appears across the transistor collector-emitter terminals. The BJT is "saturated" if IC reaches its maximum value along the load line (IB > 100 μA). Therefore, the transistor can be operated as an OFF switch with IB = 0 μA and as an ON switch with IB = 100 μA. WebThis is a demonstration of an NPN transistor. The emitter is at ground, and the base and collector voltages can be controlled using the sliders at right. Move the mouse over the transistor to see labels for the three terminals. The base-emitter junction acts like a diode . Little current flows into the base unless it is above about 0.6V.

WebCircuit Description. This circuit demonstrates how to improve the switching speed of BJTs using a speed-up capacitor. Both the turn-on and turn-off times of the BJT are reduced. The speed-up capacitor works as follows: When the input is at low state and the capacitor is fully discharged, the voltage across its plates is 0 V. WebBJT: npn BJT: pnp EMNG 1013 – Electronic Devices Page 4 When transistors are used in switching applications, they are usually operated in either the “cutoff” or “saturation” region. In the Cutoff mode, a BJT effectively behaves like an open switch and there is no current flow in the collector circuit.

WebThe most important characteristic of the BJT is the plot of the collector current, IC, versus the collector-emitter voltage, VCE, for various values of the base current, IB as shown on the circuit on the right. IC = φ (VCE, IB) for constant IB. BJT Common Emitter - Output Characteristics; Initially set rheostat Rh1 = 1 Ω and rheostat Rh2 = 1 Ω.
