Mosfet current mirror.

1. The point of a current mirror is the programming of Iout by the gate voltage from an identical device. If Iin flows through M3 it develops a gate voltage which is in common with the gate voltage on M4. As a result Iout through M4 is the same as Iin through M3. The second current mirror below M3/M4 formed by M1/M2 follows the same principle.1 Apr 2018 ...

The whole deal of the current mirror is to ensure that. a) the current through the first MOSFET is the desired current. That is achieved via IREF. b) gate/source voltage of both MOSFETs is identical. That is achieved by connecting them.
