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

摘要

This article presents a design of current differencing transresistance amplifier (CDTRA). It can be controlled of output voltage gain by R m . 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.
