Advances in Science, Technology and Engineering Systems Journal, Volume 8, Issue 1, Page # 131–137, 2023; DOI: 10.25046/aj080116
Abstract:

This communication proposes a grounded immittance function simulator that, depending on the proper choice of the passive components, can simulate parallel-type impedances of the R-L, R-C, and L-C forms. Only two grounded passive components and two voltage differencing buffered amplifiers (VDBAs) are used to implement the suggested circuit. All three simulated equivalent elements, namely Req,…
