What is Optoelectronic Devices? Optoelectronics is the technology that combines optics and electronics and the devices based on this technology are known as optoelectronic devices. These devices include emitters, sensors…
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…
What is Focusing Device in Cathode Ray Oscilloscope and why it is required? Because of the mutual repulsion between the electrons, the convergent beam coming out from the accelerating anode…
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.…
Construction and Working of Zener Diode: Zener diode, also sometimes called the breakdown diode, is a P-N junction diode specially designed for operation in the breakdown region in reverse bias…
Difference between Zener Breakdown and Avalanche Breakdown: The difference between Zener Breakdown and Avalanche Breakdown is given in table below Zener Breakdown Avalanche Breakdown This is observed in zener diodes…
Breakdown Voltage of PN Junction Diode: When an ordinary P-N junction diode is reverse biased, normally only very small reverse saturation current flows. This current is due to movement of…
Explain Steady State Conditions in Semiconductor: Explain Steady State Conditions in Semiconductor - When the P-N junction is forward biased, current flows quite freely P to N in a P-N…
