In this paper, a method for reducing the parasitic impedance effects of the current feedback operational amplifiers (CFOAs) in an inductor simulator at low frequencies is proposed. Also, two novel grounded inductors employing a current follower (CF) and a second generation current conveyor (CCII) are given to illustrate the parasitic reduction technique clearly. The low frequency restrictions of the proposed inductors due to terminal parasitic resistances can be improved by using the presented parasitic impedance reduction technique. SPICE simulations show that the presented inductor employing CFOAs in a voltage-mode (VM) band-pass and high-pass filter application has lower parasitic effects at low frequencies. In addition to simulation results, experimental test results are given to verify the theory.

SUMMARYThree new grounded capacitor current mode low-pass filters using two inverting second-generation current conveyor (ICCII) or one double output ICCII are given. The circuits employ the minimum number of passive circuit components, namely two resistors and two capacitors. The circuits are generated from three new voltage mode low-pass filters realized with the ICCII. A new grounded capacitor CCII+ current mode low-pass filter is generated from one of the new voltage mode low-pass filters employing two ICCII−. A new grounded passive component low-pass filter with independent control on Q and using three ICCII+ is also introduced. Spice simulation results based on using the 0.5 m CMOS model are included to support the theoretical analysis.

Using a single current feedback amplifier (CFA) device, two new variable frequency sinusoidal RC oscillators are presented. The transadmittance pole of the device (AD-844) has been utilized in the design for generating sine wave signals covering a range of 1 MHz ≤ f 0 ≤ 31 MHz. Under open-loop conditions, both circuits exhibit resonance characteristics at moderate Q-values (1 ≤ Q ≤ 9). These responses have been experimentally verified with hardware circuit implementation and PSPICE macromodel simulation.
