I have a question.
I know Iss as a Current Source is only for ideal situation bcus it has infinite impedance so infinite CMRR value.
and if I use NMOS as a Current Source, it has a finite impedance so would have less CMRR value.
Are there any other features like advantages, disadvantages when I use NMOS as a current source in differential amplifier?
