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 Q1 is shorted to its gate. This means that VG...
This makes N-channel depletion MOSFETs a perfect constant current source. N-channel depletion mode MOSFET features N-channel depletion mode MOSFET portfolio Infineon’s range of N-channel depletion mode MOSFETs are available in voltages from 60 V up to 600 V. Thanks to the depletion type MOSFET...
Constant current biasing: Constant current biasing involves utilizing a constant current source to bias the MOSFET. The current source provides a fixed current to the MOSFET's drain circuit, ensuring that the MOSFET operates in its linear region. Therefore, it's important to note that MOSFETs are...
