چکیده
This paper proposes two first-order all-pass filters using DDCCs as active elements, one resistor and one capacitor. Both proposed filters have two DDCCs, one grounded resistor and one grounded capacitor. Thus the two topologies are having minimum number of components and there is no need for matching constraints on passive components. The performance of the proposed circuits is examined using PSPICE simulations with the model parameters of a 0.5 μm CMOS process. Obtained results demonstrate excellent agreement with theoretical values.

Two DDCC Based Cascadable Voltage-Mode First- Order All-Pass Filters
In this paper, four new voltage-mode first-order all pass filters are proposed. Each circuit employs two differential difference current conveyors (DDCC) and two passive components with no matching condition. The proposed circuits offer high-input and low-output impedance, low active and passive sensitivities, which is a desirable feature for the voltagemode systems. Non-ideal analysis and para...

This paper presents a voltage mode cascadable single active element tunable first-order all-pass filter with a single passive component. The active element used to realise the filter is a new building block termed as differential difference dual-X current conveyor with a buffered output (DD-DXCCII). The filter is thus realized with the help of a DD-DXCCII, a capacitor, and a MOS transistor. By ...

This paper introduces four new resistorless circuits of first-order current-mode all-pass filter (CMAPF) based on dual-X current conveyor transconductance amplifier (DXCCTA). All the four circuits use a single DXCCTA and a capacitor for their realization. The main features of the proposed CMAPFs are: use of minimum active and passive components, resistorless realization, electronically adjustab...
متن کاملSingle DV-DXCCII Based Voltage Controlled First Order All-pass Filter with Inverting and Non-inverting responses
In this paper, a new voltage controlled first order all-pass filter is presented. The proposed circuit employs a single differential voltage dual-X second generation current conveyor (DV-DXCCII) and a grounded capacitor only. The proposed all-pass filter provides both inverting and non inverting voltage-mode outputs from the same configuration simultaneously without any matching condition. Non-...
متن کاملGeneration of Current Conveyor-Based All-Pass Filters from Op Amp-Based Circuits [Transaction Briefs - Circuits and Systems II: Analog and Digital Signal Processing, IEEE Transactions on
In this brief, it is shown that two of the recently reported voltage mode and current mode current conveyor-based all-pass circuits can be generated from the well known single input op amp all-pass configuration. It is also found that two other voltage mode current conveyor-based all-pass circuits are related directly to the differential input op amp all-pass structure. Several new grounded cap...
