General Description 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. |
