Testing pulse drain current of a MOSFET
What's a good rig to test the pulse drain current of a MOSFET? I'm thinking using a gate driver very abruptly raise the \$V_{GS}\$ from 0 to the \$V_{GS\_max}\$ for the same period in time as in the ...

Widlar current source
I need help solving this problem. I believe the current in the left side of the circuit equals the current in the right side. Therefore, $$K(V_{gs1} - V_t)^2 = 4K(V_{gs2} - V_t)^2$$
I also know \$V_{...
