In this paper, various topologies of fully differential second-generation current conveyor (FDCCII) are presented. The proposed blocks are useful in mixed-mode applications where fully differential signal processing is required. The FDCCII combines the advantages of both second-generation current conveyor (CCII) and differential difference amplifier (DDA), which is further utilized to realize Universal Biquad filters.

AbstractThis study presents a high common-mode rejection ratio (CMRR), and high power-supply rejection ratio (PSRR) current-mode instrumentation amplifier (CMIA) to overcome the limitations of existing differential voltage second-generation current conveyors (DVCCII)-based CMIAs in achieving high CMRR. The design is based on a fully differential second-generation current conveyor block with a novel circuit design following by a current subtracting stage. The CMIA is designed and laid out in 130 nm CMOS technology operating under ± 1.2 V supply voltage in Cadence software. The post-layout simul

In this paper, a new circuit solution of analogue pseudo-differential second-order all-pass filter operating in the voltage mode is presented. Pseudo-differential, since both input and output terminals are differential, however, the circuit topology features single-ended structure. As active elements the differential difference current conveyors and second-generation current conveyors are advantageously used. The proposed filter features quality factor control without disturbing the polefrequency using single passive element. The designed circuit is less complex compared to fully-differential

This paper aims to introduce a novel Fully Differential second generation Current Conveyor (FDCCII) and its application to design a novel Low Power (LP), very high CMRR, and wide bandwidth (BW) Current Mode Instrumentation Amplifier (CMIA). In the proposed application, CMRR, as the most important feature, has been greatly improved by using both common mode feed forward (CMFF) and common mode feedback (CMFB) techniques, which are verified by a perfect circuit analysis. As another unique quality, it neither needs well-matched active blocks nor matched resistors but inherently improves CMRR, BW,

Two novel resistorless structures of a first-order voltage-mode all-pass filter are presented in the paper. Both the structures employ a fully differential second-generation current conveyor (FDCCII) as the primary active element, in addition to an active resistor. A grounded capacitor is the only passive component used in both the structures. In both the structures, CMOS realization of FDCCII is utilized; hence, these structures are CMOS compatible. Some of the other highly demanded features possessed by the presented all-pass structures are: a simple circuit topology, electronic tunability,

SummaryThis paper introduces a second‐order voltage‐mode (VM) multiple‐input single‐output (MISO) universal filter and a second‐order current‐mode (CM) single‐input multiple‐output (SIMO) multifunction filter. The introduced VM MISO universal filter includes a single current feedback operational amplifier (CFOA) and a single voltage follower as active elements, while the introduced CM SIMO multifunction filter contains two CFOAs. Both introduced circuits are orthogonally controllable. In other words, the quality factors can be controlled through a single resistor without affecting the resonanc

In this paper, a novel translinear loop based, high performance Complementary Metal-Oxide-Semiconductor (CMOS) second-generation differential current conveyor (DCCII) is introduced. By using super source follower transistors, very low equivalent impedances are obtained at input terminals xn and xp. In addition, new voltage-mode (VM) and current-mode (CM) first-order all-pass filters (APFs) are proposed to highlight the performance of the designed CMOS DCCII.

In this study, a second-generation positive current conveyor (CCII+)-based analog circuit is proposed for the electronic implementation of a different dynamical system which is an adaptation of the chaotic Lorenz differential equation set. The proposed circuit is more cost-effective and contains less active and passive elements than the circuit obtained by applying the classical parallel synthesis method with opamps. Mathematical analyses and SPICE simulations are performed for chaotic phase portraits and bifurcation diagrams. The proposed dynamical circuit is implemented on the board by using
