Hi All,

I have made a current mirror circuit as attached below with Rin as 5K,Vin =15Vdc

CM.png.

Vo = 24 to150Vdc.

IRef=(15-Vgs)/(5K+RDS)

As per my calc IRef=2.2mA Approx.

I assume the same current should mirrored in Iout irrespective of the voltage given @ Vo.

Mosfet Used: Si7956Dp (Dual N-channel MOSFET in a single package)

But i see a large variation in current Iout.

Can someone guide me to resolve this issue,

Thanks
