本文介绍这种简单的CCII—电流传送器,该传送器在浮动导抗(FI)模拟装置领域中很有用。图1给出两个电流源的传送电路,在假设运算放大器为理想运算放大器和电阻比满足r_1/r_3=r_2/r_4=r/r_1的条件下可以得到:
This article describes this simple CCII-current transmitter that is useful in the field of Floating Conductance (FI) simulators. Figure 1 shows the two current source transmission circuit, assuming that the op amp is the ideal op amp and the resistance ratio to meet r_1 / r_3 = r_2 / r_4 = r / r_1 conditions can be obtained:
