Mar 23, 2021 · The common source requires a circuit to split the input signal into two complimentary halves to drive each FET. Left: two NMOS. Switching: Since NMOS are faster, have lower capacitance, lower RdsON, etc, than PMOS, this circuit generally gives best performance for switching if you care about speed, RdsON, or cost. MOSFET Transistors or Metal Oxide-Semiconductor (MOS) are field effect devices that use the electric field to create a conduction channel. MOSFET transistors are more important than JFETs because almost all Integrated Circuits (IC) are built with the MOS technology.

That's not entirely correct, M2 wants to make 100 uA flow, it depends on M1 if that's going to happen. If M1 is set to slightly more than 100 uA, for example 101 uA, then M2 will "win" and 100 uA will flow.
