About

The Switched-Cap Filter Component is a 2nd-order inverting filter using the Universal Analog Block (UAB). The filter input is sampled at a specified sample rate resulting in a "stepped" output waveform. User-defined parameters such as the sample rate, corner frequency, center frequency, and bandwidth are realized as a set of capacitor values. A high bandwidth operational amplifier from the Continuous Time Block (CTB) is used to buffer the filter output.

The versatile filter module offers a wide range of functionalities, including 13-bit signed input data processing, low pass, high pass, band pass, and band stop filtering options, continuous-time output, automatic sample rate optimization, customizable filter response graphs in both frequency and time domains, and an optional input for changing the filter output polarity, with the added convenience of a comparator output for zero-crossing detection.
