Low-pass filters are systems that allow the passing without attenuation of signals with frequency below the cutoff frequency, while attenuating those with frequency above it. The amount of attenuation the signals with higher frequency suffer is dependent on their frequency and the order of the filter. In this chapter low-pass SC filters based on the continuous-time version of the Sallen-Key low-pass filter [8] will be presented and discussed when using ideal components. Higher order low-pass SC filters using cascaded sections will also be discussed in this chapter.
