Amplification in Transistor: Current Amplification in Transistor - We already know that a transistor can be used for current amplification. A small change in the base current (ΔIB) produces a large…
Transistor Voltage and Current: The Transistor Voltage polarities for an npn transistor are shown in Fig. 4-10(a). As well as conventional current direction, the direction of the arrowhead indicates the…
Transistor Operation: pnp and npn Transistor Operation - A junction transistor is simply a sandwich of one type of semiconductor material (p-type or n-type) between two layers of the opposite type.…
Microwave Transistors: Silicon bipolar transistors were first on the microwave scene, followed by GaAs field-effect transistors. Indeed, FETs now have noticeably lower noise figures, and in the C band and…
Transistor RF Amplifier Circuit: A radio receiver always has an RF section, which is a tunable circuit connected to the antenna terminals. It is there to select the wanted frequency…
Transistor Buffer Circuit: The Fig. 15.12 shows the Transistor Buffer Circuit. In these Transistor Buffer Circuit, transistor is used as a switch. It can be switch ON or OFF with…
Switching Transistor: The characteristics of modern Switching Transistor are specially suited to the functional requirements mentioned already. These along with the other Semiconductor production of static relays. The properties particularly…
Weighted Converter Using Transistor Switches (Current Switch): Figure 17.19 (a) shows a circuit diagram of a weighted converter, using transistor switches. When the D bit is high (logic 1), it…
