A Novel Active Circuit Building Block: Electronically Tunable Differential Difference Current Conveyor (EDDCC) and Its Application to KHN Filter Design

摘要

In this study, a generalized differential difference current conveyor namely electronically tunable differential difference current conveyor (EDDCC) is presented. A simple EDDCC structure is given. As an example, an electronically tunable Kerwin-Huelsman-Newcomb (KHN) filter is designed using EDDCCs in order to verify the versatility of the novel building block. SPICE simulations prove the proper operation of both EDDCC and KHN filter.
