A Programmable Impedance with High Resolution

Dai Le (Group of managing Postgraduates of Engineering Institute,AFEU,Xi'an,710038)  
Instroduces a simple and efficient circuit, it adopts two MDACs which transform digital code input into resistance and reactance The circu it with high resolution is equivalent to digital programming impedance at the port The circuit can be used in dynamic skin impedance stimulation, programmmable filter, signal generator, digital meterage electric bridge, impedance criterion
