Current Mirror Circuit Mosfet. This same thing is created for the 2n6660 mosfets. 1 4 thus by controlling the geometry of the two mosfets one can control the ratio of the two drain currents.
Even when the transistors are not matched such a circuit is called a current mirror courtesy of sedra and smith. This is basic circuit. An important feature of the current mirror is a relatively high output resistance which helps to keep the output current constant regardless of load conditions.
Ds gs t v vv so if t gs v v then the mosfet is in saturation.
In next videos we will cover cascode current mirror wilson current mirror etc. In this method a reference current is generated by a circuit and then replicated at other circuits by current mirror or current steering. In next videos we will cover cascode current mirror wilson current mirror etc. A common name for this circuit is a current mirror you can probably see why the current generated by the right hand transistor mirrors i e is similar to the reference current flowing through the left hand transistor.
