[Kevin Darrah] wanted to make a simple 3.3V regulator without using an integrated circuit. He wound up using two common NPN transistors and 4 1K resistors. The circuit isn’t going to beat out a ...

Transistors are inevitable parts of Electronic circuits. The success of a circuit design lies in ... T1 is a general purpose NPN transtior like BC 548. A potential divider comprising R1 and R2 bias ...

Applications for muting circuits abound. Included are synthesizers ... What is unique about the bipolar muting transistor? The standard NPN transistors is symmetrical in that it consists of 3 layers, ...

Circuit diagrams often show transistors in switching circuits. For an ideal NPN transistor, the switch-on voltage at the base is typically 0.6V (acceptable range is 0.6V to 0.8V). This means that ...

An NPN transistor has a layer of P-doped semiconductor ... Active region: BJT operates in this zone for amplifier circuits because the transistor can act as a fairly linear amplifier.
