Now I am using the standard biasing which includes a MOSFET transistor and resistor for the current mirror biasing
Although the cascode current mirror can often be used to increase the output impedance and the precision of the current mirror. but what I am considering about now is a robust current supply
But with such kind of current mirror, the current supply biasing T1 and R is very sensitive to the process variations, which I can observe from worse case simulations.
So I am wondering how can I obtain a current mirror which is very robust
