Web6 jan. 2024 · Basic Point-Contact Transistor Structure . There are essentially two basic types of point-contact transistors, the npn transistor and the pnp transistor, where the n and p stand for negative and positive, respectively. The only difference between the two is the arrangement of bias voltages. WebCalculate the potential vEat the emitter of the transistor using vB. For an npn transistor, vE= vB−0.65V, and for a pnp transistor, vE= vB+0.65V. 3. Calculate the emitter current iEusing the emitter voltage vEand the rest of the circuit. 4. Assume that iC≈ iEand analyze the rest of the circuit. • Because we know vE, we usually know iEas well.
