Hi there,

I am currently studying about current mirror by my self. I came across a question. I attempt to solve the question but I don't know whether it is correct or wrong.

Please check the method and reply me whether the method is correct or wrong.

Best Regards

 

Your solution looks good.
But in reality ro = ( Va + Vce) / Ic and you have to include ro of the lower BJT and re of the lower BJT.

And next time use forum build in attachment manager.
