Astable Multivibrator Definition and its Working: The multivibrator circuit which has no stable state is called the astable multivibrator. The two states of operation of astable multivibrators are quasi-stable (temporary)…
Difference Between Thyristor and Thyratrons: Before the discovery of thyristors, thyratrons were used for industrial control, but now they have been replaced by the thyristors because of the following drawbacks…
Complementary Symmetry Push Pull Amplifier: The use of transformers, at input as well as at output ends, in the push-pull amplifier shown in Fig. 17.25 makes it bulky and expensive…
Pin Photodiode - Definition, Working and Applications: The PIN photodiode is one of the most common photodetectors, since the depletion-region thickness (intrinsic layer) can be tailored to optimize the quantum…
Integrated Injection Logic (IIL or I2L) Circuit: It is the latest entry into the bipolar saturated logic field. It uses no biasing and loading resistors at all. Resistors require lot…
Transistor Lead Identification and Testing: Transistor Lead Identification and Testing - After the transistor has been manufactured, as already discussed, leads of, typically, gold, aluminium, or nickel are then attached…
Important Points Regarding Working of Transistors: The noteworthy points regarding working of transistors are summarized below. 1. Current conduction in N-P-N transistor is by electrons and the conventional current flow…
Transistor Terminals (Emitter, Collector and Base): As mentioned already, transistor is a single crystal in which there are two P-N junctions, as shown in Fig. 10.1. The idea behind is…
