Hello~all,
Can you help me answer my doubts?
The sinusoidal signal in the simulated picture produced by ICL8038( This is the data-sheet of LCL8038: http://www.kynix.com/uploadfiles/pdf0125/ICL8038.pdf ) in the actual circuit. The another two resistances I used in actual circuit are Constantan resistances --10milliohm. However the wave which tested by the real oscilloscope is so mass and it’s so different from the effect of simulation.
Does anyone know what it occurred?

We really need to see your full actual circuit.
It occurs to me that a load of 20 milliohm would short out the signal.
In some case Proteus is more tolerant than the real thing,
and sometimes less tolerant.
What is the circuit for ?

Hi, ExperimenterUK
I have found reason. When I used small resistance instead of big resistance,The driving ability to produce sine-wave of ICI8038 is not enough,so the wave is mass. After I decrease the sine wave amplitude, the wave is normal.
Thank you for you help.
