Abstract :
A novel instrumentation amplifier (IA) is presented in this article. The proposed IA possesses improved performance in comparison with the common current conveyor-based IAs. It consists of two differential voltage current conveyors (DVCCs) and two resistors. The non-ideal effects of the active devices are discussed. Performances of the proposed circuit are confirmed through HSPICE simulation. The simulated results show that the common-mode rejection ratio (CMRR) of the proposed CMIA is 102 dB up to 6.13 MHz in TSMC 0.18μm 1P6M CMOS technology with 1.8V DC power supply.
