A simpler circuit for characterizing JFETs
The circuit presented by Cor van Rij for characterizing JFETs is a clever solution. Noteworthy is the use of a five-pin test socket wired to accommodate all of the possible JFET pinout arrangements...
Accuracy loss from PWM sub-Vsense regulator programming
I’ve recently published Design Ideas showing circuits for linear PWM programming of standard bucking-type regulators in applications requiring an output span that can swing below the regulator’s sense voltage...
Next-generation of optical Ethernet PHY transceivers deliver precision time protocol and MACsec encryption for long-reach networking
The rise of smart factories, remote monitoring and connected infrastructure are increasing the demand for advanced networking systems that can operate over long distances and in challenging environments...
Circuit makes square deal
A classic nonlinear analog function is the squaring circuit. It’s useful in power sensing, frequency multiplication, RMS computation, and many other odd jobs around the lab bench...
Boost controller from Diodes Incorporated featuring four-channel current sinks and diagnostic functions for backlighting in automotive applications
Diodes Incorporated introduces the AL3069Q, an automotive-compliant high-efficiency 60 V boost controller for backlight applications...
A precision, voltage-compliant current source
It has long been known that the simple combination of a depletion-mode MOSFET and a resistor made a simple, serviceable current source...
Toshiba drives next-generation automotive electrification with a cost-effective gate driver IC for three-phase BLDC motors
Toshiba Electronics announces commercial sample shipments of its innovative gate driver IC, the TB9084FTG, tailored for three-phase brushless DC (BLDC) motors...
A non-finicky, mass-producible audio frequency white noise generator
This project made me feel a kind of kinship with Diogenes, although I was searching for the item described in the title rather than for an honest man...
