A New Simulated Grounded Inductor with Two-Terminal Active Devices

In this study, a new simulated grounded inductor (SGI) is developed. It has a simple structure because it employs two-terminal active devices (TTADs). Moreover, it has a minimum number of passive elements, considering the TTAD-based configurations. However, there is a single passive element-matching constraint for two resistors. Derived from the developed SGI, a second-order voltage-mode universal filter application is given. With proper connection of inputs, it yields band-pass (BP), high-pass (HP), low-pass (LP), all-pass (AP), and notch filter (NF) responses. The performance of the developed circuits is verified through the SPICE simulation program. Additionally, an experimental test result is given for the developed SGI.
