Colpitts Oscillator using Transistor Circuit: The Colpitts oscillator circuit is a superb circuit and is widely used in commercial signal generators up to 100 MHz. The basic Colpitts Oscillator using…
Transistor Circuit Configurations (CB, CE, CC): As already mentioned, a Transistor Circuit Configurations is a three-terminal device (having three terminals namely emitter, base and collector) but we require four terminals—two…
Transistor Circuit Noise: Unwanted signals at the output of an electronics system are termed noise. The noise amplitude may be large enough to severely distort, or completely swamp, the wanted…
Transistor as a Switch Circuit Diagram and Working: The Transistor as a Switch Circuit Diagram and Working can be explained with the help of its output characteristics. Figure 31.2 shows…
Transistor Detector Circuit Working Principle: It is possible to achieve amplitude demodulation by using a three-element electronic device. A typical example of such a configuration is illustrated in Fig. 22.51.…
Darlington Pair Transistor - Circuit Diagram and its Workings: A very popular connection of two BJTs for operation as one "superbeta" transistor is the Darlington connection. In practice, the two…
Direct Coupled Transistor Amplifier - Operations and Equivalent Circuit: Direct coupling is essential for very low frequency (below 10 Hz) applications such as photoelectric current, thermocouple current etc. Thermocouples are…
What is Single Stage Transistor Amplifier? - Circuit Diagram and its Workings When only one transistor with associated circuit is used for increasing the strength of a weak signal, the…
