Current Differencing Transresistance Amplifier (CDTRA) and its Application for Analog Signal Processing

This article presents a design of current differencing transresistance amplifier (CDTRA). It can be controlled of output voltage gain by Rm. The output terminals offer both in current and voltage signals. Furthermore, the circuit is theoretically temperature-insensitive which is preferable to use in a temperature variation work. The PSpice simulation results confirm the CDTRA. In addition, an application in a grounded inductance simulator is disclosed. The total power consumption is 3.53mW at ±3 V power supplies.
