Abstract
AbstractElement level simulation using a switched capacitor (SC) have been employed mainly for inductance simulation and there have been quite a few reports on the higher‐order immittance simulation which is a current research topic of analog filters.This paper proposes two types of SC circuits—ungrounded frequency‐dependent negative resistance (FDNR) and frequency‐dependent negative inductance (FDNL)—synthesized by bilinear transformation and the simulation results by the SC circuit analysis program (SWITCAP) are compared with the theoretical values. Moreover, the experimental results on the discrete components are shown which agree well with theoretical values.The circuits use unity gain buffers (UGBs) as active devices due to their simple synthesis, and they are controlled by a two‐phase clock. Moreover, the parasitic capacitors which are derived from bottom plates of an integrated capacitor have no effect on the performance except for one capacitor which determines the element values.
