Abstract :
A novel input stage, which is insensitive to parasitic capacitances and incorporates the necessary sample-and-hold (S/H) function, is described for bilinear lowpass and bandpass switched-capacitor ladder filters. The resulting circuit needs less operational amplifiers than existing filters.
