Abstract

Amplifiers, crucial in analog circuitry, are assessed based on transmission gain and frequency response. Lower transmission gain yields flatter frequency response and less distortion, crucial for signal fidelity. Various amplifier types excel in distinct applications. Feedback amplifiers utilize loops to control gain, stability, and linearity, often employing operational amplifiers. They offer adjustable gain through feedback resistance ratios, crucial for diverse applications. Balanced amplifiers handle balanced signals, canceling noise and interference, ideal for long-distance transmission due to their dual-input setup that mitigates common-mode noise impact. Distributed amplifiers, prevalent in high-frequency domains, distribute gain across multiple stages along a transmission line. Despite requiring more transistors, they offer robust performance and adaptability, crucial in high-interference environments. Power amplifiers, divided into linear and switching types, deliver amplified signals with minimal distortion. Class A, AB, B, and C amplifiers balance gain, efficiency, and linearity, often necessitating compromises in design. Their distinct features and capabilities make them indispensable components across various industries, driving advancements in the same environment. Studying the comparison of distributed amplifiers, balanced amplifiers, power amplifiers, and feedback amplifiers in the same environment is significant for gaining a deeper understanding of their performance and applications in electronic circuits. The specific content may include comprehensive analysis and comparison of these amplifiers’ working principles, performance metrics (such as gain, bandwidth, noise, etc.), power consumption, stability, cost, etc. Such research helps guide the selection and design in engineering practice to meet the requirements of different application scenarios and promotes further development of amplifier technology.
