In order to build a large-scale quantum computer that works, scientists and engineers need to overcome the spontaneous errors that quantum bits – or qubits – create as they operate. Scientists encode ...

The fun part about logic gates is that there are so many ways to make them, with each approach having its own advantages and disadvantages. Although these days transistor-transistor logic (TTL) is the ...

Forward-looking: Semiconductors are essential for today's electronics, providing computational capabilities and the ability to control electric signals. They are also highly complex and costly, so ...

Why it matters: For decades, scientists have dreamed of building computer chips that use light instead of electricity to process information. While our current silicon chips are incredibly fast, ...

Logic gates process data and generate outputs using Boolean algebra and truth tables (Figure 1) to define operations for all binary input combinations: 0 (false, low) and 1 (true, high). Figure 1. A ...

I've decided to use the 2N3904 transistor as its gain of roughly 150 at collector currents between 5 to 10 mA is very appropriate. The resistors used are all power rated for a maximum dissipation of ...
