Document Type and Number:
WIPO Patent Application WO/2023/226150
Kind Code:
A1
Abstract:
The present application provides an RC low-pass filter and a method for fast establishment of a filter. The RC low-pass filter comprises: an at least first-order RC low-pass filter and at least one charge transfer unit, the at least first-order RC low-pass filter and the at least one charge transfer unit being connected in series; the at least one charge transfer unit implements charge transfer of the at least first-order RC low-pass filter by means of multiple capacitors, multiple switches, and multiple energy transfer modules, to obtain an establishment time of a preset narrow bandwidth and a preset RC low-pass filter. The method for fast establishment of a filter is used for fast establishment of the RC low-pass filter. In the present application, a charge transfer unit is provided in an RC low-pass filter, so that fast establishment of an RC low-pass filter having a narrow bandwidth and a short establishment time is implemented.
