This paper introduces a new type of CMOS-based current conveyor: current controlled fully balanced second generation current conveyor (CFBCCII) element which has a pair of differential Y terminals, a pair of differential X terminals and two pairs of Z terminals. The proposed circuit offers electronic tuning possibilities by means of a current adjustable intrinsic resistance at its X terminal. A...

An ultra low-power high-speed rail-to-rail buffer amplifier with improved current summing circuit is proposed for LCD source drivers. By placing two complementary differential pairs in parallel, it is possible to obtain a rail-to-rail input stage. Then, a current summing circuit with two embedded comparators is proposed. With the proposed current summing circuit, the output stages will be turne...

In the present work, a new sensor for morphine (MO) measurement, based on modification of screen-printed carbon electrode (SPE) by using magnetic core shell manganese ferrite nanoparticles was reported. The electrochemical behaviour of MO was investigated in phosphate buffer solution (pH 7.0) by voltammetry. The electrochemical response of the modified electrode toward morphine was studied by m...

In current study,a hydrogel based on biocompatible polymerwas prepared. The functionalization of polyvinyl alcohol (PVA)with epichlorohydrin(ECH) to produce epichlorohydrin-g-polyvinyl alcohol (PVA/ECH) as a suitable macroinitiator for atom transfer radical polymerization (ATRP) reaction was investigated.ThenN-vinyl pyrrolidone (NVP) waspolymerized on the surface of macroinitiatorin presence of...

It is well known that fully differential signal processing more advantageous than single-ended in a noisy environment, and widely used audio, video other applications. This paper introduces new configuration contains first-order low-pass (LP) filter, high-pass (HP) all-pass (AP) all present within the same circuit design. The proposed simple employs only one multiple-output current differencing...
