dc.description.abstractIn this paper, a new realization of current-controlled current feedback operational amplifier with balanced voltage outputs (BO-CCCFOA) is presented. A resistorless grounded lossless positive inductance simulator (PIS) using two BO-CCCFOAs and a grounded capacitor is reported. The resulting equivalent inductance value of PIS can be adjusted either via change of input intrinsic resistance of BO-CCCFOAs by means of biasing currents or by order of fractional-order capacitor (FoC). FoCs of order = (0.25; 0.5; 0.75; 1) were emulated via 5th-order Foster II RC network and values optimized using modified least squares quadratic (MLSQ) method. In frequency range 30 kHz - 30 MHz the obtained phase angle deviation of FoCs and mean values of corresponding relative phase error are below ±1 degree and ±4.3%, respectively. Considering the bandwidth for phase angle deviation less than 3 degree, the proposed fractional-order PIS operates over two decades. The behavior of the PIS circuit with various orders was tested via implementation in RLC ladder prototype of voltage-mode high-pass filter. Theoretical results are verified by SPICE simulations using TSMC 0.18 m level-7 LO EPI SCN018 CMOS process parameters with ±1 V supply voltages.en
