You probably have needed to match impedances and levels from time to time. Perhaps you want to connect a consumer computer’s sound card to your console; or you need to lower a balanced output level to ...

This gate-drive transformer (GDT)circuit allows the drive signal to the MOSFET to range from 50% down to 0%, while still offering a fast turn-off that cannot be accomplished with a simple load ...

Shortly after installation, the simple water-leak-detector circuit in this Design Idea saved the day and hundreds of dollars. The average life expectancy of a hot-water heater is about 10 years. It’s ...

A recently granted patent (Publication Number: US11777412B2) describes a switching power supply apparatus that includes a switching circuit and an even number of transformers. The switching circuit ...

Low-power circuits commonly use transformerless power supplies. However, the use of earth grounds in many of these circuits creates a serious problem that is often ignored. The very popular Microchip ...

The creative new approach could lead to more energy-efficient machine-learning hardware. On a table in his lab at the University of Pennsylvania, physicist Sam Dillavou has connected an array of ...
