This paper presents fifteen distinct practical realizations for dual-X second generation current conveyor (DXCCII) using commercially available integrated circuits. Detailed comparisons and results are presented to verify the utility of proposed realizations. The catalog of proposed realizations is a first attempt and is expected to be useful for testing newly developed circuits based on dual-X...

A multi-output second generation current conveyor (MOCCII), that can be used to realized first, second and third generations current conveyors, is proposed. The MOCCII consists of a CMOS differential stage for the voltage input, push-pull stage and the improved cascode current mirrors for the current output. Feedback techniques are proposed in order to provide a voltage gain of 0.991, a current...

This paper presents two novel Floating Current Source (FCS)-based CMOS negative second generation current conveyor (CCII−) realizations suitable for very large scale implementation. The proposed realizations provide high voltage and current tracking accuracy, as well as large voltage and current transfer bandwidths. Simulation results show that the ̄rst proposed wideband CCII− bandwidth is about...

This paper presents a fully-integrated NEMS resonator together with a compact built-in CMOS interfacing circuitry. The proposed low-power CCII circuit allows measuring the mechanical frequency response of the nanocantilever structure in the MHz range. Detailed experimental results at different DC biasing conditions and pressure levels are presented for a real mixed electro-mechanical system int...

Dust lift-off from conveyors forms a significant environmental and operational problem for operators in the mining, power generation and process industries. One means of reducing dust lift-off is to provide airflow deflectors or other aerodynamic modifications to the conveyor. A CFD model has been developed to take into account the effect of wind direction, velocity and conveyor guarding on the...

We study a minimal model for the flow of granular material on a conveyor belt consisting of a staircase-like array of K vertically vibrated compartments. Applying a steady inflow rate Q to the top compartment, we determine the maximum value Qcr(K) for which a continuous flow through the system is possible. BeyondQcr(K), which depends on the vibration strength and the dimensions of the system, a...

The micro-conveyor is a 9 × 9 mm manipulation surface able to move millimeter-sized planar objects in the four cardinal directions using air flows. Thanks to a specific design, the air flow comes through a network of micro-channels connected to an array of micro-nozzles. Thus, the micro-conveyor generates an array of tilted air jets that lifts and moves the object in the required direction. In ...

In this paper a multiple output second-generation current conveyor (MOCCII) is presented. The main advantage of the proposed general circuit architecture over a typical structure, well known in the literature, is the use of a high passband multiple output current amplifier block instead of cascaded current mirrors. It gives similar frequency responses for all the outputs of the current conveyor...
