    This article presents a dual slope analog-to-digital converter (ADC) using second generation current conveyor (CCII)-based integrator. In comparison with the previously reported dual slope ADCs with grounded capacitor, the proposed configuration offers simpler structure and fewer components while utilizing the positive reference voltage. Experimental results are given to confirm the operation of the proposed ADC. ICIC International © 2010 ISSN.

    This article presents an effective method to realize interface circuit for single active element resistive sensors. The realization is composed of op-amp in conjunction with current conveyors. Surpassing the previous circuit using only single current conveyor, the proposed configuration affords significant improvement in accuracy. PSPICE simulation results are used to confirm the performance of the proposed circuit. © 2010 ICIC International.
