Power Amplifier Linearization

Power Amplifier Linearization In high-efficiency power amplification, linearization is critical to maintaining signal fidelity. Distortion—especially in RF and audio systems—can severely degrade performance and lead to compliance issues in communication systems. This research area investigates techniques to linearize power amplifiers, such as predistortion, negative feedback, and adaptive biasing. These methods are applicable in both analog […]

Low‑Noise Analog Amplification

Low‑Noise Analog Amplification Low-noise analog amplification represents a fundamental research direction in signal conditioning, particularly for applications requiring high precision and fidelity. These include biomedical sensors, scientific instrumentation, and high-end audio systems. The goal is to amplify small analog signals without introducing significant additional noise. This involves minimizing thermal, flicker, and shot noise through circuit […]
