Actively Simulated Floating Lossless Inductor for Short Range Wireless Communication

Abstract

This communication describes the resistorless simulation of the floating lossless inductor using three voltage differencing buffered amplifiers (VDBAs) and one grounded capacitor. The circuit employs only a grounded capacitor, and no other extra resistor element is employed. Thus, it is suitable for further communication integrated front-end circuit design in short-range wireless and application. The realized equivalent inductance value of the simulated inductor can be changed electronically via the external biasing currents of the VDBAs. Sufficient simulation results with the PSPICE program are provided to validate the functionality of the realized inductor. In addition to establishing the practical operation of the simulator, the measured test results obtained from hardware implementation using readily available integrated chips (ICs) are also included.

Inductance Simulators and Their Application to the 4th Order Elliptic Lowpass Ladder Filter Using CMOS VD-DIBAs

“…A comparison of the proposed inductance simulators with other inductance simulators [31][32][33]44,[46][47][48][49][50][51][52][53][54][55][56][57][58][59][60], is shown in Table 3. It can be seen that most of the simple inductance simulators using one active building block only perform grounded-type simulations [31,48,[57][58][59][60].…”

“…The grounded inductance simulators in [33,52,53,56] use more than one active building block. The floating inductance simulators in [33,51,56] require three active elements. The prosed inductance simulators in [49,52,54,58] use a floating capacitor, but the proposed inductance simulators consist of a grounded capacitor, which is a benefit from an integration point of view.…”

“…With two active and passive elements, the proposed floating inductance simulators can perform three functions, as a lossless inductor, series inductor-resistor, and parallel inductor-resistor. However, the inductance simulators realized in [31][32][33][46][47][48][49][50][51][52][53][54][55][56][57][58][59][60] cannot perform three functions with the same number of active and passive elements. The inductance simulators in [50,55] were realized from the active building block with a multiple output terminal.…”

“…The inductance simulators in [46,53,57,59] require a strict matching condition of the passive element. Most of the published papers [31][32][33]44,[46][47][48][49][50][51][52][53][54][55][56][57][58][59][60] on inductance simulator design do not show the procedure employed to design the topology. Therefore, new researchers or designers will not understand how to obtain the completed circuits.…”
