Re: how do I calculate the current in a cascode current mirr
I have ever set up such a circuit under tsmc .18 process. For a moderate W (such as several um), the current is around 1uA, If u want to get more than 2mA current, W maybe quite large. Furthermore, if we consisder the worst case, such as 1.6V ss corner 120 centidegrade, the task is even more difficult. By the way, I have also try to increase L to get lower Vth and bigger Vdsat, but it will cost more area.....
