Operational Transconductance Amplifier (OTA): The operational amplifiers considered up to this point have been voltage amplifiers. The input signal is a voltage and the output signal is a voltage. Another…
Switch Mode Power Supply (SMPS) or Switching Regulators: Switch Mode Power Supply (SMPS) - The regulated power supplies described earlier were basically linear voltage regulators. A linear voltage regulator possesses…
Regulated and Unregulated Power Supply: Almost all electronic devices used in electronic circuits need a dc source of power to operate. The source of dc power is used to establish…
What is a Digital Integrated Circuit? In an integrated circuit, components such as diodes, transistors, resistors, inductors etc. are integral parts of the chip. And on surface of this chip,…
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…
Base Spreading Resistance: With two depletion layers penetrating the base, the base holes are confined to the thin region of P-type semiconductor illustrated in Fig. 10.12. The resistance of this…
Transistor Action : Operation of PNP Transistor: Transistor action - Transistors of both types (P-N-P and N-P-N) behave exactly in the same way except change in biasing and majority carriers.…
What is a thermistor? - Definition, Symbol and V-I Characteristics: The word thermistor is a combination of thermal and resistor. A thermistor is a resistor with definite thermal characteristics. Most…
