In this article we elaborately discuss a simple to built yet awesome 1000 watt amplifier circuit, which could be easily upgraded to achieve upto 2000 watt output. It uses relatively fewer components and could be quickly set up for getting a massive 1000 watt power output on any 4 ohm, 1kva loudspeaker. This circuit was … Read more1000 watt to 2000 watt Power Amplifier Circuit
Common emitter amplifier is the the most commonly used transistor configuration can be seen in Fig. 3.13 below for both pnp and npn transistors. This configuration is known as common-emitter configuration because the emitter is common, or becomes the reference terminal to both the input and output stages (meaning common to both the base and … Read moreCommon Emitter Amplifier – Characteristics, Biasing, Solved Examples
In general, an amplifier can be defined as a circuit designed to boost an applied low power input signal into a high power output signal, as per the specified rating of the components. Although, the basic function remains the same, amplifiers could be classified into different categories depending on their design and configurations. Circuits for … Read moreUnderstanding Amplifier Circuits
