    "abstract": "This article analyzes the design of a low-noise amplifier intended as the\ninput front-end for the measurement of the low-frequency components (below 10\nHz) of a 50 Ohm source. Low residual flicker is the main desired performance.\nThis feature can only be appreciated if white noise is sufficiently low, and if\nan appropriate design ensures dc stability. An optimal solution is proposed, in\nwhich the low-noise and dc-stability features are achieved at a reasonable\ncomplexity. Gain is accurate to more than 100 kHz, which makes the amplifier an\nappealing external front-end for fast Fourier transform (FFT) analyzers.",
