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 ...

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 ...

Researchers have built working transistors from graphene nanoribbons less than a nanometer wide, achieving room-temperature ...

A team of Chinese researchers has built a ferroelectric transistor with a gate length of just 1 nanometer that runs on 0.6 ...

The circuit aims to produce a power amplifier with the use of an operational amplifier NE5534 at its input compared to classic designs which use differential amplifiers. NE5534 – a high performance ...

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 ...
