Chapter 6: Transistors and Gain William Marypnp transistor c e I be I ce=βI be Figure : Basic operation of npn (left) and pnp (right) bipolar junction transistors. Let's summarize the conditions required for an npn transistor to conduct (the "transistor rules"): 1. Vbe > 0. Since this is a diode, Vbe should be roughly when it is conducting. 2. Vbc < 0. This is a back ...

Making Transistors Learn About Electronics Home PageSilicon Planar Transistors. Germanium based diffused alloy transistors were widely used in the 1950s, but by the 1960s they were largely superceded by transistors that use silicon as the semiconductor material and the methods of production changed to the planar (layered) type of construction, illustrated in Figures to These ...

Fuzz Card Original PNP Hybrid FuzzCard "plugin fuzz" concept Fuzz is a touchy thing. Most players have their own idea of what the ideal Fuzz should sound like. This is due in part to the fact that the original FuzzFace was not a consistent product, there were different versions (Silicon NPN, germanium PNP, custom mods, etc..) and individual units sounded different from one another.
