In the circuit shown in Fig.2 ,6 volt DC supply is provided ... Collector current = 100mA – 98mA = 2 mA The condition is just reversed in the case of a PNP transistor as shown in Fig.4. The ...

In the early days, PNP bipolar transistors were common, but the bulk of circuits you see today use NPN transistors. As [Aaron Danner] points out, many people think PNP transistors are “backward ...

Let’s look at another simulation to see how that works. In this circuit, a PNP transistor sources current. The base voltage is about 0.7 V less than the emitter voltage. So with 10.3 V on the ...

Applications for muting circuits abound. Included are synthesizers ... Base drive is best provided via a PNP transistor connected to the positive 15 to 24V rail –a series resistor limits the base ...

The PNP transistor has one N region between two P ... Active region: BJT operates in this zone for amplifier circuits because the transistor can act as a fairly linear amplifier.

The npn and pnp transistors used in the circuit should be high current- gain (hfe > 100) devices with minimum 2-A continuous current drive capacity (see the figure). This ensures an output stage ...
