A New Method for SC Circuit Synthesis Based on the voltage Inversion Concept

A new general method for SC circuit synthesis, based on the voltage inversion concept, is presented. According to the proposed method, first- and second-order SC equivalent admittances are developed and subsequently a number of SC subcircuits are derived. These subcircuits are used in the derivation of high order filters. Emphasis is given to integrator and second-order circuits. All the proposed circuits are fully parasitics free and compare favourably with known circuits. Two design examples of high order filters are also given. One of them was further designed in an IC form.
