A simple FET radio receiver circuit showing FET biasing. The gate is biased at ground potential through the inductor, and the source is held above ground by the current in the 5K resistor.

This comprehensive collection features over 300 JFET-based circuit designs, serving as a valuable resource for engineers, students, and hobbyists interested in analog circuitry.

Commercial curve tracers have existed for decades. But designers without access to one can create a simple circuit that uses a function generator and oscilloscope to generate JFET transfer and ...

Qorvo has picked depletion-mode (normally-on) silicon carbide JFET technology to build a 750V 4.3mΩ transistor for circuit breakers, and put it in a 10 x 12mm surface-mount TOLL package. “It was ...

If you ever work with a circuit that controls a decent amount of current, you will often encounter a FET – a Field-Effect Transistor. Whether you want to control a couple of powerful LEDs ...

This circuit is effective for low-power laser diodes but may not be so for diodes with power dissipation greater than 150 mA. The maximum cutoff current of the JFET sets this limit. If it becomes ...

SiC JFETs are extremely robust transistors. Examples include the depletion-mode trench JFETs developed by UnitedSiC, which have no built-in body diode. Combining a SiC JFET with a low-voltage ...

The Heatseeker takes the signal from your guitar and processes it through an all-analogue JFET circuit. The pedal runs on 9V DC from a pedalboard power supply but internally boosts the voltage to 27V.

FREMONT, Calif., March 6, 2025 /PRNewswire/ — Linear Systems, a leader in monolithic dual JFETs and small-signal discrete semiconductor manufacturing, announces the release of JFET Circuit ...
