%X A new method for switched-capacitor filleter (SCF) realization by using the linear transformation techique is described. It is shown that using VCVS equivalent transformation to revise the original LC ladder filter, sixteen basic sections are obtained. By using them, it is possible to realize all four kinds of filters-lowpass, highpass, bandpass and bandstop filter. As example, the paper presents their designs. A Nth order filter only requires N amplifiers and is insensitive to the parasitic capacitors. The experimental results of 3rd order lowpass and 6th order bandpass SCF are given and agree well with the theory.
