Published:2011/7/14 20:21:00 Author:Joyce | Keyword: Multifunctional , Active , Filter | From:SeekIC

This circuit is composed of three operational amplifiers and resistance components, and its main characteristic is that it can get filtering properties of high-pass, low-pass and band-pass. In addition, once the values of Rf、Cf are changed, the bandpass characteristics can be ensured in a wide range without any interference between the circuit gain and the value of Q . This circuit is simple and easy to adjust . Also it is stable.
