This paper presents two new first-order voltage-mode all-pass filters using a single-current differencing buffered amplifier and four passive components. Each circuit is compatible to a current-controlled current differencing buffered amplifier with only two passive elements, thus resulting in two more circuits, which employ a capacitor, a resistor, and an active element, thus using a minimum of active and passive component counts. The proposed circuits possess low output impedance, and hence can be easily cascaded for voltage-mode systems. PSPICE simulation results are given to confirm the theory.

Electronically Tunable

In this paper, a new electronically tunable quadrature oscillator (ETQO) based on two modified versions of current feedback amplifiers (CFAs), the so called double current controlled CFA (DCC-CFAs) is presented. The frequency of oscillation (FO) of the proposed voltage-mode (VM) ETQO is electronically adjustable by current gain or by varying the intrinsic resistance of the X terminal of the active element used. The condition of oscillation (CO) is adjustable by current gain independently with respect to frequency of oscillation. Simultaneous control of current gain and intrinsic resistance allows linear control of FO and provides extension of frequency tuning range. In the proposed circuit all the capacitors are grounded. The use of only grounded capacitors makes the proposed circuit ideal for integrated circuit implementation. The presented active element realized by using BiCMOS technology and the behavior of proposed circuit are discussed in details. The theoretical results are verified by SPICE simulations based on CMOS ON-Semi C5 0.5 μm and bipolar ultra high frequency transistor arrays Intersil HFA 3096 process parameters.

This paper presents first-order voltage-mode filters using a single current conveyor with an additional X-stage, and passive elements. The new circuits have multifunction capability, and also realize low-shelf, high-shelf and band-shelf functions. The study is carried out on the effects of non-idealities, parasitic elements, and loading on the performance of proposed circuits. Active and passive sensitivities are also analyzed. The active element, extra-X current conveyor used for designing new circuits is simpler than most of the one active element and two passive elements’ based circuits. Detailed comparisons are carried out with relevant available works, and the new circuits are found to be more compact and exhibit higher frequency performances. The simulation results using 0.25[Formula: see text][Formula: see text]m CMOS parameters with [Formula: see text]1.25[Formula: see text]V power-supply are shown to verify the proposed circuits. The proposed circuits are also verified through simulations. Experimental support is given using AD-844 ICs to strengthen the validity of the proposed circuits.

This paper presents two new first-order voltage-mode (VM) cascadable all-pass (AP) sections, employing two differential voltage current conveyors (DVCCs) and three grounded passive components. Both circuits possess high input and low output impedance, which makes them easily cascadable. Non-ideality aspects and parasitic effects are also studied. As an application, a quadrature oscillator is designed using the proposed circuit. The proposed circuits are verified through PSPICE simulations using 0.5 μm CMOS parameters.

Quadrature Oscillators

A number of sinusoidal oscillators using current differencing buffered amplifiers (CDBAs) have been reported in the literature. However, only three of them are canonic quadrature oscillators (i.e., requiring two capacitors). The aim of this letter is to present additional realizations of single/dual-resistance-controlled quadrature oscillators using CDBAs. Four voltage-mode quadrature oscillators are proposed, which provide the following advantageous features: (i) use of reduced and canonic component count, viz. two CDBAs, three/four resistors and two capacitors, (ii) all passive components are grounded or virtually grounded, which is favorable from integration point of view and (iii) independent and non-interactive resistor control of the condition of oscillation (CO) and the frequency of oscillation (FO). Simulation results verifying the workability of the proposed circuits have been included.
