Quasi Complementary Output Stage: The Quasi Complementary Output Stage was originally developed because complementary high-power transistors were not readily available. Despite the fact that such transistors are now available, the Quasi Complementary Output Stage circuit…
Dual Input Balanced Output Differential Amplifier: The dual input balanced output differential amplifier configuÂration is shown in Fig. 20.2. In the given circuit two input signals vin1 and vin2Â are applied to the bases B1 and…
Tariffs and Power Factor Improvement Interview Questions and Answers: 1. What is meant by tariff? Ans. Tariff means the schedule of rates or charges. Tariff, in case of electric supply, means the schedule or rates…
What is Extrinsic Semiconductor? Intrinsic (or pure) semiconductor by itself is of little significance as it has little current conduction capability at ordinary room temperature. However, the electrical conductivity of intrinsic semiconductor can be increased…
Equivalent Circuit of a Diode: It is usually advantageous to replace a device or system by its equivalent circuit. An equivalent circuit of a device or a system is a combination of electric elements properly…
Testing of DC Machine or Swinburne Test: Testing of DC Machine or Swinburne Test - Machine efficiency, in general, has been discussed already. The approach here will be to apply the general principles for the…
Addressing Modes of 80186: The 80186 provides eight different types of addressing modes to specify operands. The operand (data) is used in the instruction to specify the addressing modes. The addressing mode byte is always…
Rotor Overheating Protection Diagram: Rotor Overheating Protection is provided only in case of large generators. It indicates the level of temperature and not the actual hot spot temperature. In the arrangement shown in Fig. 11.20,…
Superposition Theorem Formula: The Superposition Theorem Formula also can be used to analyses ac circuits containing more than one source. The superposition theorem states that the response in any element in a circuit is the…
Varactor Diode Operation and Characteristics: Varactor Diode Operation and Characteristics were first used in the early 1950s as simple voltage-variable capacitance and later for frequency modulation of oscillators. They thus represent a very mature semiconductor…
