In electronics, the Gummel plot is the combined plot of the base and collector electric currents, and , of a bipolar transistor vs. the base–emitter voltage, , on a semi-logarithmic scale. This plot is very useful in device characterization because it reflects on the quality of the emitter–base junction while the base–collector bias, V bc ...
A multiple-emitter transistor is a specialized bipolar transistor mostly used at the inputs of integrated circuit TTL NAND logic gates. Input signals are applied to the emitters . The voltage presented to the following stage is pulled low if any one or more of the base–emitter junctions is forward biased, allowing logical operations to be ...
Darlington Transistor (NPN-type) In electronics, a Darlington configuration (commonly called as a Darlington pair) is a circuit consisting of two bipolar transistors with the emitter of one transistor connected to the base of the other, such that the current amplified by the first transistor is amplified further by the second one.

Figure 1: Basic NPN common collector circuit (neglecting biasing details). In electronics , a common collector amplifier (also known as an emitter follower ) is one of three basic single-stage bipolar junction transistor (BJT) amplifier topologies , typically used as a voltage buffer .

For NPN open collector outputs, the emitter of the NPN transistor is internally connected to ground, [1] so the NPN open collector internally forms either a short-circuit (technically low impedance or "low-Z") connection to the low voltage (which could be ground) when the transistor is switched on, or an open-circuit (technically high impedance ...
Sziklai pair that acts like a single NPN transistor with collector C, emitter E, and base B. In electronics , the Sziklai pair , also known as a complementary feedback pair , is a configuration of two bipolar transistors , similar to a Darlington pair . [ 1 ]
