Abstract:

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,an d the other for faint floating curent sign als.As there is no DOCCⅢchip on sale at present,four novel realization schemes of DOCC Ⅲ are then proposed SO that computer simulations an d experiments can be carried out,with the corresponding results confirming that the proposed circuits of DOCCⅢand the realized rectifiers are feasi-ble.

Key words: floating rectifier, third-generation curent conveyor, precision measurement
