I constructed a 1:1 npn current mirror with BJTs with a reference current of 0.5 mA. When I increase the load resistance, the output current drops from 0.5 mA to 0.497 mA (this is in the active mode). I'm supposed to plot the output voltage against the output current to find the output impedance but my slope is negative. Is this plausible or did i fuck up?
