The concept of optical computing is reintroduced with an important new twist — optical computing not as a digital machine, but as an analog engine able to serve as a hardware accelerator for existing ...

Today it seems that everything electronic is digital—a reasonable assumption considering it’s hard to find a turnable knob anywhere and values are displayed in digits everywhere. The underlying ...

A computer that processes analog data is known as an analog computer. Analog computers store information in physical quantities in a continuous format and use measurements to perform computation.

We have always had programmable analog circuits. Any circuit that makes outputs change as a function of inputs is in some way programmable. Examples include gain change as a function of voltage or ...

Say the word “analog” to most EEs, and thoughts turn to op-amps, power devices, I/O, or signal conditioning circuits. But, the system beyond the circuit is also full of “analog,” if we include ...

Could analog artificial intelligence (AI) hardware – rather than digital – tap fast, low-energy processing to solve machine learning’s rising costs and carbon footprint? Researchers say yes: Logan ...
