BGD902,112 linear amplifiers are used for amplification and gain of signal types in various applications. This article will discuss its application field and the working principle of BGD902,112.Application Field:The wide bandwidth of BGD902,112 allows it to be used in a variety of video and sound applications, such as high definition television, digital video broadcasting, and digital audio/video production and processing. The low noise and high linearity of the amplifier allow it to be used in high-end professional video and sound applications, such as broadcast television and post production. The high gain and wide bandwidth also make it suitable for low power imaging and vision applications.Working Principle: The working principle of BGD902,112 amplifiers is based on linear amplification of the input signal. This linear amplification is achieved by using two stages of amplification. The first stage is a voltage amplifier which amplifies the input signal voltage, while the second stage is a current amplifier which amplifies the current through the circuit. The two stages of amplification are combined to produce an output signal with an increased gain and wide bandwidth.The first stage of amplification is a voltage amplifier, which is composed of transistors connected in a differential configuration. The transistors are connected so as to amplify the applied input signal voltage. The output of the first stage is then fed to the current amplifier stage, which is composed of two transistors connected in a common source configuration. The current amplifier amplifies the current through the circuit, resulting in an increased gain and wide bandwidth.The output from the amplifier is then rectified to provide a DC output voltage, which is used to power the circuit’s other components. The output is then fed to the subsequent stages in the signal chain, such as audio and video processing, or to the desired output device.Conclusion:BGD902,112 linear amplifiers are well suited for a variety of video and sound applications, such as those in broadcast television and post production. Their wide bandwidth, low noise, and high linearity allow them to produce high-quality outputs and excellent results. The two-stage configuration of the amplifiers allows for a high gain and wide bandwidth, while their rectified DC output makes them suitable for use in low power imaging and vision projects.
