Abstract

The current-mode circuit technique to design a bi-directional current transceiver for remote control systems and telemetering systems is presented in this paper. The proposed transceiver can transmit and receive the industrial standard current signal 4-20mA at the same time using two wires connection. The realization method is based on a second generation current conveyor (CCII) and a current mirror, which can be implemented using a commercially available device. To demonstrate the performance of the proposed scheme, the transceiver was simulated by the use of the PSPICE analog simulation program. The simulation results verifying the circuit performance are agreed with the expected values. The crosstalk of the proposed transceiver of about .63dB is observed.
