Ebers–Moll model for an NPN transistor. [28] I B, I C and I E are the base, collector and emitter currents; I CD and I ED are the collector and emitter diode currents; α F and α R are the forward and reverse common-base current gains. Ebers–Moll model for a PNP transistor Approximated Ebers–Moll model for an NPN transistor in the ...
The Type 575 Transistor-Curve Tracer displays the dynamic characteristic curves of both NPN and PNP transistors on the screen of a 5-inch cathode-ray tube. Several different transistor characteristic curves may be displayed, including the collector family in the common-base and common emitter configuration. In addition to the transistor ...
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.
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.

"The disadvantages are that more different power supply voltages are needed, and both pnp and npn transistors are required." [9] Instead of alternating NPN and PNP stages, another coupling method employed Zener diodes and resistors to shift the output logic levels to be the same as the input logic levels. [17]
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 ]
Transistor packages are mainly standardized, but the assignment of a transistor's functions to the terminals is not: other transistor types can assign other functions to the package's terminals. Even for the same transistor type the terminal assignment can vary (normally indicated by a suffix letter to the part number, q.e. BC212L and BC212K).
Diode–transistor logic (DTL) is a class of digital circuits that is the direct ancestor of transistor–transistor logic. It is called so because the logic gating functions AND and OR are performed by diode logic , while logical inversion (NOT) and amplification (providing signal restoration) is performed by a transistor (in contrast with ...
