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 … WebBJT, digital circuits history, dynamic operation, introduction to BICMOS, MOS fan in, fan out, MOS logic circuit characterization, MOS power delay product, MOS power dissipation, MOS propagation delay, and types of logic families.
