SummaryIn this communication, two new positive lossy series inductor simulator circuits using single current differencing buffered amplifier (CDBA), one capacitor, and three resistors are presented. In both the proposed circuits, the inductance value is independently controllable through a grounded resistor, which may be implemented using a voltage‐controlled resistor (VCR), facilitating electronic tuning. Moreover, one of the circuits presented utilizes the intrinsic resistance (internal resistance available at input ports p and n) of the CDBA, thereby enabling electronic control and establishing the inductor simulator as canonical. Both the circuits are analyzed for non‐ideal behavior by taking into account the parasitic elements of CDBA and compared with their ideal counterparts. To demonstrate the efficacy of the proposed series RL simulator circuits, SPICE simulations are performed using CMOS CDBA, and the performance of the proposed circuits is evaluated by designing a lead compensator. The simulation and experimental results of the proposed circuits, along with the application examples employing CDBA realized with the off‐the‐shelf available IC AD844, have also been corroborated.

“…The main problem of the low pass passive filter, usually, is the size and cost of the inductors, where the passive components (inductance, capacitive) is not suitable to design in a low pass filter for medical applications, additionally, the drawback of the passive inductor is a requirement of excessive chip area. In addition, passive inductors are vulnerable to process fluctuations and suffer from resistive losses [9]- [12].…”

“…The researcher in [11] presented a circuit configuration that can act like a grounded impedance simulator/grounded impedance scaling circuit it can simulate electronically tunable grounded resistance/capacitance/inductance/FDNR and also work as a grounded impedance multiplier circuit, which can scale up/scale-down the value of arbitrary grounded impedance with an electronically controllable multiplication factor. In [12] described a grounded lossy inductance (grounded parallel RL network) simulator configuration employing two Current differencing differential input transconductance amplifiers (CDDITAs), one resistance (grounded), and one capacitance (grounded) is completely free from active/passive component matching conditions and its behavior is studied considering non-ideal current-voltage transfer ratios. To validate the usefulness of the presented parallel resistor inductance (RL) simulator some filter designs are developed.…”

<p>In this paper, a designed circuit used for low-frequency filters is implemented and realized the filter is based on frequency-dependent negative resistance (FDNR) as an inductor simulator to substitute the traditional inductance, which is heavy and high cost due to the coil material manufacturing and size area. The simulator is based on an active operation amplifier or operation transconductance amplifier (OTA) that is easy to build in an integrated circuit with a minimum number of components. The third and higher-order Butterworth filter is simulated at low frequency for low pass filter to use in medical instruments and low-frequency applications. The designed circuit is compared with the traditional proportional integral controller enhanced (PIE) and T section ordinary filter. The results with magnitude and phase response were compared and an acceptable result is obtained. The filter can be used for general applications such as medical and other low-frequency filters needed.</p>
