Only eight lithography masks to create a low-power custom logic chips, compared with 20+ for CMOS, is the claim of Nottingham-based fabless chip start-up ‘Search For The Next’ (SFN). As such, ...

Combining GaN transistors with silicon-based digital circuits enables complex computing functions built directly into power ...

In multiple-output power supplies in which a single supply powers circuitry of vastly different current draws, two perplexing steps are sensing the current that each output draws and deactivating the ...

When it comes to portable devices and mobile computing, power consumption is a critical factor that can make or break a product. There has been some notable progress towards all-day battery life in ...

The digital age has resulted in a succession of smaller, cleaner and less power-hungry technologies since the days the personal computer fit atop a desk, replacing mainframe models that once filled ...

Last week, it was announced that Cambridge GaN Devices (CGD) will lead a €10.3m European project (‘GaNext’) to develop fast-switching intelligent GaN power modules. But who is this small UK company ...

The following automatic battery-charger design is created with a circuit that could qualify as the simplest window comparator ever built around a single transistor (see the figure). It starts charging ...

Last time on Circuit VR, we looked at creating a very simple common emitter amplifier, but we didn’t talk about how to select the capacitor values, or much about why we wanted them. We are going to ...
