  "textContent": "There is provided a denoising circuit connecting to two pins of a chip. The denoising circuit includes a shielding branch, a driving branch and an intermediate capacitor. The shielding branch is connected between a first pin of the chip, a ground voltage and a shielding metal. The driving branch is connected between a second pin of the chip and a load. The intermediate capacitor is connected between the shielding branch and the driving branch. The first pin and the second pin are used to respectively output a sinusoidal signal.",
