MOSFET cascode current
You can implement this with non-matched MOSFETs it just won't perform as well. You should at least try to pair M1 and M2, and M3 and M4 i.e. choose the same part for each of these two pairs. BTW the same part is NOT matching as there will be some degree of variation in certain characteristics for the same part number e.g. IDSS. In some cases you can manually measure these characteristic and &quot;find&quot; a pair.
Devices with a closer match can be found on ICs that have multiple MOSFETs. These will be manufactured the same and experience the same environment e.g. temperature considerations as they are on the same die. Look at diodes.com/assets/Datasheets/ds31757.pdf for an example.
