Switched Capacitor Filters

Switched capacitor filters are electronic filters that use capacitors and switches to create a desired frequency response. A switched capacitor filter works by using switches to connect and disconnect capacitors in different combinations, which creates different filter circuits. This allows the filter to be easily reconfigured to create different frequency responses, such as low pass, high pass, or band pass. Switched capacitor filters are commonly used in applications where it is important to filter out unwanted frequencies, such as in audio and telecommunications systems. They are attractive because they can be easily reconfigured, which allows them to be used in a wide range of applications.
