摘　　要：采用1块具有双输出端的第三代电流传输器(DOCCⅢ)及4个整流二极管开发了两个微弱浮地精密全波整流器:一个适合处理微弱浮地电压信号;另一个适合处理微弱浮地电流信号.因目前市面上尚无DOCCⅢ芯片出售,为了便于计算机仿真和实验研究,给出了4种实现DOCCⅢ器件的新方案.文中对所提出的精密全波整流器进行了计算机仿真和实验研究,结果证实了所提出的DOCCⅢ实现电路及浮地精密全波整流器的正确性.Two faint floating precision all-wave rectifiers are realized by using a third-generation current conveyor with dual outputs （ DOCC Ⅲ ） and four rectification diodes. One of the rectifiers is suitable for faint floating voltage signals, and the other for faint floating current signals. As there is no DOCC Ⅲ chip on sale at present, four novel realization schemes of DOCC Ⅲ are then proposed so that computer simulations and experiments can be carried out, with the corresponding results confirming that the proposed circuits of DOCC Ⅲ and the realized rectifiers are feasible.
