A near‐DC measurement and modelling of low‐frequency noise in electronic components

Abstract Low‐frequency noise, generated inherently by the number or mobility fluctuation of carriers, is a crucial concern for design analog and digital circuits. Unified modelling based on experimental validation near‐DC noise in amplifiers long‐standing open problem. This article develops model low‐frequency deriving new bounds carrier capturing releasing. According to proposed model, measurement system suggested that operates wide frequency range even at very low frequencies. The noise‐tolerant, since amplifier selected acceptable levels. Among advantages are independence from specialized structural models each component cost system. evaluation results show method leads promising improvement measuring superior conventional normalized root mean square error indicator. Findings reveal can estimate flicker around DC frequency, agrees reasonably with circuit.
