However, if your MCU has 1.8 V GPIOs and your FET’s Vgs doesn’t quite cut it, an NPN transistor is a more advantageous solution, since that one will work as long as you can source the whatever ...

The JFET (Q1) has a sloppy range for the Vgs off parameter (3 to 6V). This tends to vary the bias clamp voltage, attack time and recovery time. For repeatable results, it is recommended that devices ...

The circuit generates two curves that describe JFET behavior. The transfer curve plots drain-source current (IDS) versus gate-source voltage (VGS) with a fixed drain-source voltage (VDS), and the ...
