The current mirror concept is the same for both mosfets and bipolar junction transistors. The basic idea is to use two identical transistors. One is configured as a diode with the drain and gate (or collector and base for BJT) connected together. When current is driven thru the diode, the diode voltage is used to drive the source/gate terminals (or emiter/base terminals for BJT) of the other transistor. If the transistors are identical and at the same temperature, then the current in the second transistor will match the first transistor that is operating like a diode.Hello,
Can someone explain the current mirror concept for mosfets?
thanks
I was able to find a schematic and analysis in my old electronics notes. Please see attached.Could you show a schematic for what you're talking about?
