Analog computing

Cells as living calculatorsUsing analog computation circuits, MIT engineers design cells that can compute logarithms, divide and take square roots.

Mimicking cells with transistorsAnalog — rather than digital — circuits could enable models of biological systems that are more efficient, more accurate and easier to build.

The surprising usefulness of sloppy arithmeticA computer chip that performs imprecise calculations could process some types of data thousands of times more efficiently than existing chips.
