Re: Constant current source vs. resistor. Differences?

Hi gronam,
The answer is better CMRR with the active constant current source. CMRR is short for Common Mode Rejection Ratio.
You can even go as far as Peufeu in France and cascode this current source again to cancel thermal distortion and the Early effect.
Its all in the conjuring-box of tricks of the solid state engineer-magician!
