EMITTER COLLECTORText Appearing After Image:Fig. 2--Transistor mechanism. is a rectitier biased stiongly in the low-conducting direction. It therefore hasa rectifying barrier in the germanium near it, which causes the collectorimpedance to be high. However, the collector can be influenced by the 370 BELL SYSTEM TECHNICAL JOURNAL emitter if the latter is arranged to emit anomalous charge carriers, thatis, carriers of the sign not normally present in the interior of the material. Equivai.kntt Circuits As has been explained by liardecn, Bratlain, and Shockley, many featuresof the transistor are nicely explained by this picture of its action; but, forpresent purposes of circuit analysis, we shall now take the purely empirical EQUIVALENT CIRCUIT EquationsNote About ImagesPlease note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original work.
