Low-Frequency Noise Mitigation Short-Term Voltage Project Details
| Abstract |
Low‑frequency noise often degrades high‑precision electronic measurements and voltage‑sweep systems, reducing signal quality during short‑term operations. To tackle this, the research investigates a predictive active‑noise‑cancellation (ANC) method built into a dual digital‑to‑analog converter (DAC) architecture. A predictive algorithm estimates the upcoming noise and creates an anti‑noise signal, which is then added to the main sweep signal using the two DACs. Because the prediction runs in real time, the system continuously compensates for low‑frequency fluctuations and drift that appear during short voltage sweeps. The dual‑DAC layout provides high‑resolution signal generation while also allocating extra hardware for noise cancellation, keeping the primary sweep signal clean. The design is evaluated by measuring noise‑reduction
efficiency, the convergence speed of the predictive algorithm, and overall signal‑to‑noise‑ratio (SNR) improvement at different sweep rates. This approach offers a solid way to improve measurement accuracy in semiconductor characterization, sensor calibration, and other precision‑instrumentation tasks where low‑frequency noise is a critical issue.
