Abstract
A current-mode active-R biquadratic filter is realized using operation al amplifiers. It is shown that the proposed circuit can realize lowpa ss, bandpass, highpass, bandstop and allpass transfer functions simult aneously without changing the circuit topology and elements. The paras itic effects of opamps on the filter characteristics are also discusse d using a two-pole model of opamp gain. An example is given together w ith results simulated with PSpice.
