Some new first-order all-pass filters using a second-generation current conveyor are reported. Two circuits have higher input impedance than reported very recently and use a grounded capacitor. Additionally two more circuits have been reported, one of which has minimum passive and active components and has the facility of single resistance tuning. The other circuit has high input impedance and uses two current conveyors but has one passive component less than the similar circuits reported earlier.

Background: Three high input impedances voltage-mode first-order filters are presented. Methods: The first proposed circuit uses one multi-output second-generation current conveyor, two resistors and one grounded capacitor. The second proposed circuit uses two second-generation current conveyors, three resistors and one grounded capacitor. The third proposed circuit uses one multi-output second-generation current conveyor, one resistor and two grounded capacitors. Results: First-order lowpass and allpass filters can be simultaneously obtained in the first proposed circuit. First-order lowpass, highpass and allpass filters can be simultaneously obtained in the second proposed circuit. The third proposed circuit can realize first-order allpass filter. Conclusion: All the proposed circuits have the advantages of high input impedances and using only grounded capacitors.

This paper presents some additional high input low output impedance analog networks realized using a recently introduced single Dual-X Current Conveyor with buffered output. The new circuits encompass several all-pass sections of first- and second-order. The voltage-mode proposals benefit from high input impedance and low output impedance. Nonideality and sensitivity analysis is also performed. The circuit performances are depicted through PSPICE simulations, which show good agreement with theory.

In this paper, a new voltage-mode (VM) multifunctional filter comprising two second-generation current conveyors (CCIIs) is proposed. The proposed filter with one input and three outputs is also composed of three resistors and two grounded capacitors. The proposed filter has high input impedance; thus, it can be easily connected with other VM circuits. The proposed filter can simultaneously provide low-pass (LP), band-pass (BP) and high-pass (HP) responses. A number of time domain and frequency domain simulation results are included to confirm the claimed theory.

To extend the existing knowledge on first-order voltage-mode all-pass filters, this paper presents two novel first-order voltage-mode all-pass sections, each employing single fully differential second-generation current conveyor (FDCCII) being used as the newly obtained fully differential voltage conveyor (FDVC), a resistor and a grounded capacitor. Both the proposed circuits possess high-input and low-output impedance feature, which makes the proposed circuits ideal for voltage-mode systems. Non-ideal study along with simulation results is given for validation.
