WebJun 6, 2016 · The MOSFET Constant-Current Source Circuit. Here is the basic MOSFET constant-current source: It’s surprisingly simple, in my opinion—two NMOS transistors and a resistor. Let’s look at how this circuit works. As you can see, the drain of Q 1 is shorted to its gate. This means that V G = V D, and thus V GD = 0 V. WebFeb 2, 2024 · What is Current Mirror? The current mirror is an analog circuit that senses the reference current and generates the copy or number of copies of the reference current, …
