Summary: Recently, many non-traditional applications of Switched-Capacitor circuits have been popularly studied. As one of those applications, we present here a new constructing 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. Furthermore, by applying those Units, an arbitrary transfer function can be easily synthesized. In addition, some algorithms to obtain useful impedances are proposed. Several SC-ISC impedances were experimentally constructed and theoretically analyzed. In particular, some kinds of simple filters and oscillators were made and tested. They were also theoretically analyzed.
