“…This paper presents a new first order VM-APS which caters to six of the above listed features. The new circuit with two active elements exhibits all the features listed from (ii) to (vii), thus offering a novel and unique addition to the field and to the rich literature on the subject [1,[5][6][7][8][9][10][11][12][13]15]. When compared to the two active element based tunable circuit realizations [9,12], the new circuit is canonical (unlike [12]) and uses a grounded capacitor (unlike [9,12]).…”

A new canonical first order voltage-mode all-pass section (VM-APS) employing a single grounded capacitor as the only passive element and two differential voltage current conveyors as the active elements is proposed. The circuit, with its attractive features of resistorless realization, voltage-controlled pole frequency and low impedance voltage output is a novel and unique offering to the field and an addition to the rich literature on the subject. PSPICE simulations are carried out in 0.5 µ CMOS technology to validate the utility of the proposed circuit.

“…The recently published all-pass filters in [17] employ two floating resistors and one grounded capacitor together with a fully differential current conveyor (FDCCII) without requiring a matching condition. However, it has neither high input impedance nor low output impedance, which is a need in cascading systems.…”

In this paper, a novel design for realizing a voltage-mode (VM) all-pass filter utilizing two differential voltage current conveyors (DVCCs) is proposed. Also, the suggested filter uses a canonical number of passive elements (one grounded capacitor and one resistor) without requiring any element matching condition. The proposed filter has high input and low output impedances, which make it suitable for cascading. The effects of the nonidealities of the DVCCs on the proposed design are investigated. As an application, a quadrature oscillator is designed using the proposed VM all-pass filter and an integrator. The proposed filter and oscillator circuits are simulated using the SPICE simulation program to confirm the theory.

This brief communication presents two current feedback op-amp (CFOA)based simple first-order mixed-mode universal filter topologies-one of them providing first-order low-pass (LP), high pass (HP), and all pass (AP)-all the three filters in voltage-mode (VM)/trans-admittance-mode (TAM) while the other one realizing the quoted three functions in current-mode (CM)/transimpedance-mode (TIM). Except the all pass filter realization from the first configuration which needs a second CFOA also as gain-of-two amplifier, in all the remaining cases of both the configurations, only a single CFOA is needed. The other notable features of the circuits are employment of only three resistors and a grounded capacitor (as preferred for IC implementation) and the availability of independent tunability of the gain (H 0 ) and cut-off frequency/pole frequency (ω 0 ) of all the three filters, in both the cases. In spite of not offering ideally infinite input impedance in VM/TAM mode and ideally zero input impedance in CM/TIM mode, the circuits still possess easy cascadability due to providing a voltage output from a low-output impedance terminal W while the current output from the high output impedance terminal Z. Non-ideal and sensitivity analyses have also been carried out. The workability of the proposed circuits has been demonstrated through PSPICE simulations and experimental results using the commercially available AD844-type IC CFOA.
