FILTER CONTROL CIRCUIT Abstract of the Disclosure A filter control circuit uses a compound FET as a resistance element. The compound FET includes parallel FETs having different gate widths to provide different drain-source resistance characteristics, which overlap to provide an extended operating region, that approaches a linear curve for the combined resistance characteristic. The control voltage used to control the compound FET may be coupled to like compound FETs in the filter being controlled. - i -
