| Abstract: | A high-performance current-mode instrumentation amplifier circuit is described in this paper. It has a high common mode rejection ratio, high gain, high accuracy, wide bandwidth and bandwidth gain-independence. It utilizes commercially available integrated circuits and is easily implemented. Experimental results show that at low frequencies a common mode rejection ratio of 120 dB is attainable. |
