Thank you, Steve.
The threshold voltage of a silicon diode is 0.7V and this is the voltage which drops across a diode. Now consider an E-MOSFET transistor which always has positive threshold voltage, V_th. Let's say V_th=0.7V. Will this 0.7V drop across the transistor in order for it to conduct? Note that the transistor will also need a certain V_ds in order to conduct. Let's assume to conduct 230μA the transistor needs V_ds=2V and has V_th=0.7V, then would this mean that the transistor needs total of 2.7V in order to conduct this current through it? Personally, I don't think V_th is the voltage which drops across a transistor; it's just the voltage which tells us that V_gs should be greater than V_th in order for it to conduct, and the only voltage drop which occurs is the V_ds one. Could you please help me with this? Thank you.
