چکیده
This paper presents a high CMRR and wideband current feedback Instrumentation Amplifier (IA). The proposed IA architecture consists of Fully Balanced Differential Difference Amplifier (FBDDA) and Differential Difference Amplifier (DDA) based on 2 generation current conveyor (CCII) with a buffer. From the simulation results evaluated by HSPICE, the proposed IA exhibits average CMRR was 109.3 dB higher than the conventional one. Furthermore, the proposed IA has higher closed-loop gain over a larger bandwidth than corresponding voltage feedback.
