- 演算增幅器의 有限한 利得-帶域幅積이 計測增幅器의 周波數特性에 미치는 영향을 줄이기 위하여 能動補償方法을 써서 演算增幅器 4個와 抵抗만으로 入力임피이던스가 높고 能動補償된 計測增幅器를 構成하였다. 實驗 結果 提案된 回路가 改善된 周波數特性을 나타내었다.
An actively compensated instrumentation amplifier reducing the effects of the finite gain bandwidth products of operational amplifiers is realized only by the use of 4 operational amplifiers and some registors. The performances of the actively compensated instrumentation amplifier are compared with those of the uncompensated one by means of the experimental results and shown to offer an improved frequency response.
