In Boost and modify square waves, we covered several methods for conditioning square waves for use with digital signals. In this final installment, we look at 555 timers, voltage regulators, op amps, ...

IN A WORLD where new technology is dominated by the movement of electrons and the manipulation of biomolecules, it is good to know that old-fashioned mechanics can sometimes get a look-in, too.

The combination of an external circuit and a low-voltage microcontroller occasionally requires a significantly higher power-supply voltage. You can use either an external boost converter to increase ...

A new type of device—a hybrid antenna with electronics developed by electrical engineers at the Georgia Institute of Technology—puts several transmitters and receivers on the same IC chip or package, ...
