The programmable standard hesistance generator
Yong Chen · 2000
This curcuit is designed for getting programmable standard resistance generatou,which is controled by CMOS IC and codified by 8421 code.It is digital,progarmmable and it's resistance can combined in any way.It is a practical mothed of program control resistors.It is widely used in testing procedure of Automotive instrument.This paper specifies the composition and priciple of the circuit.
