WebThe VBE voltage of the simple diode connected transistor of figure 14.1 (a) can be used to generate a regulated current reference as well, as shown in figure 14.3. In this circuit the simple diode connection around Q 1 is replaced by emitter follower Q 2. The VBE of Q 1 is impressed across R 2 and the resulting current flows through Q 2 to ... A transistor is a semiconductor device with at least three terminals for connection to an electric circuit. In the common case, the third terminal controls the flow of current between the other two terminals. This can be used for amplification, as in the case of a radio receiver, or for rapid switching, as in the case of digital circuits. The transistor replaced the vacuum-tube triode, also called a (thermionic) valve, which was much larger in size and used significantly more power to …

Webtions are critical to the operation of the BJT. BJTs are also simply known as bipolar transistors. 8.1 INTRODUCTION TO THE BJT A BJT is made of a heavily doped emitter (see Fig. 8–1a), a P-type base, and an N-type collector. This device is an NPN BJT. (A PNP BJT would have a P+ emitter, N-type base, and P-type collector.)
