Abstract:
A solid electrolytic capacitor with a protective structure, which includes stacked capacitor elements electrically connected to the positive and negative terminal. A packaging material such as synthetic resin is used to encapsulate the capacitor elements, the positive terminal, and the negative terminal. Before packaging, a protective layer is formed by a colloid material, which covers the main body of the capacitor that includes the capacitor elements, the positive terminal, and the negative terminal. The protective layer provides a better seal and relieves the external pressure exerting on the capacitor during the packaging process. The protection prevents structural damage to the capacitor's main body while reducing the risk of short-circuits and excessive current leakage.
Abstract:
A system and method of correcting baseline wander (BLW) are disclosed. An analog-to-digital converter (ADC) converts an analog input to a digital output, and a slicer maps the digital output to one of a plurality of predefined values. A BLW correction unit generates a BLW correction value according to a difference between an input and an output of the slicer. A correction controller generates a fine correction value and a coarse correction value according to the BLW correction value. Specifically, the fine correction value is used to correct the digital output of the ADC, and the coarse correction value is used to correct the analog input of the ADC.
