摘要：
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 2nd 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.
