摘要
PURPOSE: A switched capacitor biquad filter is provided to improve the flexibility and the precision of the filter by changing a sampling frequency and controlling the band width of the filter. ;CONSTITUTION: A first switched capacitor(SC1) is in connection with the input terminal of a first switched operational amplifier(OP1). A first capacitor(C1) and a second switched capacitor(SC2) are in parallel connection with the input terminal of a second switched operational amplifier(OP2). A third switched capacitor(SC3) is connected between the output terminal of the first switched operational amplifier and the input terminal of the second switched operational amplifier. A second capacitor(C2) is connected between the output terminal of the second switched amplifier and the first switched capacitor. A third capacitor(C3) is connected between the output terminal of the second switched operational amplifier and the third switched capacitor.;COPYRIGHT KIPO 2011
