Open-circuit voltage transfer-function synthesis using the generalized positive impedance converter

An open-circuit voltage transfer-function synthesis procedure is presented that realizes any arbitrary real rational function in the complex variable s. The procedure makes use of an active device referred to as the generalized positive impedance converter (GPIC). The synthesis procedure yields a network realization that 1) requires the minimum number of capacitors necessary for the synthesis, 2) is compatible with integrated-circuit fabrication techniques, and 3) has low sensitivity.
