WebThe low-pass filter’s Q factor, gain (G), and corner frequency (f C) determine the amplifier’s minimum allow-able gain bandwidth (f GBW). When finding the Q factor, first identify the type of filter approximation (Butterworth, Bessel, Chebyshev, etc.) and the filter order[2]. As previ-ously specified, the corner frequency is 10 kHz. In this WebOct 6, 2009 · Theoretically, as the numbers of order increased, the filter will approximate ideal filter characteristics. The challenges are; by increasing the filter's order, it will increase the circuit complexity and the cost. In order to reduce the circuit complexity, the Sallen-Key topology has been selected since the topology requires fewer components.
