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 ...

Solid-state device technologies, which are available to the amplifier designer, fall, broadly, into three categories: bipolar junction transistors (BJTs) and junction diodes; junction field effect ...

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 ...

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, ...

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 ...
