A new current mode implementation of a balanced-output-signal generator

This paper presents a new current mode implementation of a balanced-output-signal generator that utilizes an operational floating current conveyor (OFCC) as a basic building block. The OFCC, as a current-mode device, shows flexible properties with respect to other current or voltage-mode circuits. The advantages of the proposed current mode balanced-output-signal generator (CMBG) are threefold. Firstly, it offers an accurate phase and amplitude performance over a wide bandwidth without requiring matched resistors. Secondly, it has a differential input and it can provide either current or voltage outputs. Finally, the proposed CMBG circuit offers a significant improvement in accuracy compared to other CMBGs based on the current conveyor. The proposed CMBG has been analyzed, simulated and experimentally tested. The experimental results verify that the proposed CMBG outperforms existing CMBGs in terms of the number of basic building blocks used and accuracy.
