Author’s note: This article shows how to derive circuit gain equations via a signal flow graph. With practice you may be able to write a gain equation by locating signal paths and loops in the ...

When we decided to become electronics engineers, we were introduced to Ohm's Law and to two enshrined methods of analyzing circuits. These were called “loop analysis” and “node analysis.” We were told ...

Power grids (PGs) have consumed an increasingly larger percentage of routing resources in recent process node generations, due to lower maximum current limits imposed by the foundry. It is not ...

Now that it takes $10 million or more to bring a device to market, focused ion beam (FIB) circuit edit has become strategically important for reducing costs, optimizing performance and functionality, ...

Nasopharyngeal carcinoma (NPC) is a central tumor with a rich lymphatic network and a propensity for bilateral cervical lymph node metastasis. There is an orderly pattern of lymph node involvement in ...
