The configuration of a common emitter transistor is widely used in most electronic circuit designs. This configuration is evenly appropriate to both the transistors like PNP and NPN transistors but NPN transistors are most frequently used due to the widespread use of these transistors. In Common Emi...
We can use three different configurations to achieve amplification with a bipolar junction transistor. While the common-emitter configuration uses the emitter as the common terminal to an ac signal, the common-collector--or emitter follower--amplifiers have the input applied to the base through a c...
The PNP transistor is of the form of a conventional vertical NPN transistor, in common base configuration, supplying base current to a lateral PNP transistor. The emitter of the vertical NPN is disposed in the emitter of the lateral PNP; the base and collector of the vertical NPN are the ...
the Darlington common base stage is used to reduce base current losses. The base current that is recovered is that of transistor 21. In FIG. 1D the base current is produced without the delay through the emitter of transistor 63 as it is in FIG. 1C. Thus, the recovered base current arri...
By utilizing an external PNP BJT transistor, the common-mode voltage range can be extended to greater than 500 V, depending on the breakdown voltage of the transistor. The current through the emitter of transistor Q1 (IOUT) is proportional to the input voltage (VSENSE) and, therefore, the ...

CONSTITUTION:PNP TRs 3, 4 are of current mirror configuration, a collector current and an emitter current of NPN TRs 1, 2 and 3, 4 are almost made equal to each other and a current flowing changing by a change in an input current flows. Then an emitter current of the TR 3 is ...
The major drawback of this topology is its limited output swing, typically on the order of 1V or more to the rail due to transistor operating voltages in the stage. Specifically, the minimal forward-bias voltage across the PNP current source (VFB-P), and the base-emitter voltage (VBE-N...
