摘要：
The realization of second-order RC active low-pass filters having cut-off frequencies in the MHz range is supported by design methods whose results are checked by means of circuit simulations. Here the Sallen and Key filter is treated using an non-inverting wide-band operational amplifier whose high-frequency parameters have to be taken into account in some detail. In addition to the extensive analysis of a circuit based on a non-ideal amplifier, also a simplified design procedure is developed which yields suitable initial filter element values for further high accuracy optimizations.
