Abstract :
The large parasitic capacitances of MOS capacitors to substrate usually degrades the performance of VIS-SC filters. It will be discussed, how the effect of such parasitics can be reduced by selection of a suitable set of network elements. Experimental results of a fully integrated 7th order low pass with only 4 op amps will be given.
