The first step in designing a microwave frequency power amplifier monolithic microwave integrated circuit on a given GaN foundry process is to select the transistor size and bias, writes Liam Devlin.

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 ...

Linear Technology's recently introduced LTC4300 chip buffers I 2 C clock and data lines to and from a hot-swappable card. This task is difficult because the IC must work bidirectionally, meaning that ...

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

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, ...

Engineering researchers have demonstrated a new transistor that switches at only 0.1 volts and reduces power dissipation by over 90 percent compared to state-of-the-art silicon transistors. One of the ...

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 ...

Microprocessors in smartphones, computers, and data centers process information by manipulating electrons through solid semiconductors, but our brains have a different system. They rely on the ...

The chipmaker will shed light on a series of changes it's making to transistors that ideally will keep a lid on the growing problem of power consumption. Michael Kanellos is editor at large at CNET ...
