What is an AND Gate?AND Gate DefinitionAn AND gate is a digital logic gate that outputs high only when all its inputs are high.Logical OperationThis gate uses logical multiplication; the output is low if any input is low, and high only if all inputs are high.AND Gate Circuit DiagramEssential for understanding how AND gates can be constructed using diodes or transistors to manipulate electrical signals.IC ImplementationAND gates are implemented in integrated circuits like the 7408 for TTL and 408

Op Amp DefinitionAn op amp (operational amplifier) is defined as a DC-coupled voltage amplifier with a high voltage gain used in various electronic circuits.Working PrincipleThe op amp amplifies the difference between two input signals, known as the differential input voltage, in its open loop operation.Closed Loop OperationIn closed loop mode, feedback is introduced to control the output signal, with positive feedback used for oscillators and negative feedback for amplifiers.Op Amp Characterist

Definition of ICsIntegrated Circuits (ICs) are defined as electronic circuits where components are permanently embedded on a semiconductor wafer.Types of ICsICs are mainly classified into analog and digital types, each serving different functions in electronic devices.Moore’s LawThis principle explains that the number of transistors on an IC doubles approximately every two years, driving technological growth.IC ManufacturingICs are produced using monolithic or hybrid technologies, each with its
