Please log in for more thread options Mosfets are like voltage controlled resistors. For a given Vgs, there is a certain Rds. Like op-amps, they'll "find" their steady state, so for example Rds changes might change the source voltage, which would then change Vgs. Think of the way an emitter follower works; you can do something similar with a mosfet to make a source follower. | ||||||||||
