Magnetic cores had some interesting uses, but a lot has changed in memory technology...
Now and then: magnetic cores
Renesas unveils first bidirectional 650V-class GaN switch for solar power inverters, AI data centers and more
Renesas Electronics introduced the industry’s first bidirectional switch using depletion-mode GaN technology, capable of blocking both positive and negative currents in a single device with DC blocking...
Over-temperature micro-power alarm
The circuit is powered for years by a single 3 volt lithium battery. It sounds an alarm when the temperature exceeds a certain point...
1-bit and 2-bit dual-supply bus transceivers from Toshiba support low-voltage level shifting
Toshiba Electronics Europe expands its 74AVC series lineup of dual-supply bus transceivers with four new 1-bit products...
Well-balanced gain, driven without pain
A subtle change to a standard circuit can enhance its usefulness – and even save a resistor...
Single switch controls sequential operation of multiple power supplies
Simple analog circuits manage multi-PSU powerup and shutdown sequences...
Infrared remote control decoder & switcher using Arduino
In this article, we learn to build a device that can decode (almost) any IR remote control and use the instructions to switch the relays (loads)...
ΔVBE thermometer outputs 1 mV/°C without calibration or op amps
Op amps tend to make analog design easy. Maybe sometimes too easy?...
Piezoelectric tap switch
This circuit uses a flat piezoelectric wafer, glued inside a plastic box, as a finger tap sensor. With each tap of a finger to the box holding the wafer, the circuit turns on and off AC or DC power to an external device...
ΔVbe + DMM = Celsius, Kelvin, Fahrenheit, and Rankine thermometer
Combining an accurate temperature sensor with a standard digital multimeter can make an inexpensive, accurate, and useful thermometer...
