Glucose Measurement Using PSoC 3
Hi to all,
I am doing glucose measurement , in this i am Interfacing IDAC, VDAC, TIA(Transimpedance Amplifier).Glucose Test Strip gives current so i am taking IDAC .
The Output Equation at TIA Vout=Vref-I*R, Normally for I=0 case Vout= Vref , but here I=0 i.e i am not connecting any thing to terminal , but i am measuring Vout, what i am getting is 0.29v, why is this strange output or else i am wrong any where.i am uploading Image of TOPDESIGN.
