A method of realizing monolithic variable linear circuit elements ispresented. The method exploits monolithic variable gain amplifiers tomodify the values of passive integrated devices. The technique describedherein realizes floating true two-terminal variable elements. A theoreticalanalysis of a variable capacitance cell is performed as a prelude to apractical design producing capacitances in the range of 4 pF to 30 pF. Theresults of theoretical analyses are compared to SPICE [1] simulations of thesubject cell, prototype circuit results are presented, and performancelimitations are discussed.
