Grounded and Floating Series-Type Lossy Capacitance and Inductance Simulators Using VDIBA(s)

This communication introduces new configurations of series-type grounded/floating R-C and R-L simulator circuits. The grounded series R-C circuit makes use of a single voltage differencing inverted buffered amplifier (VDIBA), in addition to one resistor and one grounded capacitor. The capacitance of the circuit can be controlled independently through a resistor without requiring any passive component matching constraints. The proposed R-L circuit uses of single VDIBA in conjunction with one capacitor and one grounded resistor, and the realized inductance can be adjusted using a grounded resistor. A notable feature of the proposed R-C and R-L circuits is that, by adding one more VDIBA, they can be transformed into a floating series R-C and R-L simulator circuits. The usability of the proposed circuits in control systems and analog systems is considered. The impact of non-idealities of VDIBA on the proposed circuits is investigated. The functionality of the presented circuits is validated using a CMOS VDIBA implemented using 0.18 µm TSMC technology parameters. Experimental results of the application examples realized using presented circuits are also provided using a VDIBA realized with commercially available ICs to corroborate the theoretical propositions.
