Recently, many non-traditional applications of switched-capacitor circuits have been studied. We present a new construction technique of a Switched-Capacitor Impedance Simulation Circuit (SC-ISC) with unity-gain buffers. Any desired impedance can be obtained by applying this SC-ISC technique. To make up a SC-ISC simply and generally, four kinds of basic constructing 'Units' and two types of 'feedback circuits' are introduced. By applying those units, an arbitrary transfer function can be easily synthesized. Algorithms to obtain useful impedances are proposed. Several SC-ISC impedances were experimentally constructed and theoretically analyzed. Some simple filters and oscillators were made and tested. They were also theoretically analyzed.
