It has been five years this month that President Obama signed an $816.3 billion fiscal stimulus package, known as the American Recovery and Reinvestment Act, into law. Has it worked? To answer this ...

A voltage multiplier is applied as a high source impedance, 36V, 300mA, 12W LED driver. The high source impedance is ideal for driving power LEDs because it accommodates variations in LED junction ...

The circuits presented here use ananalog switch—such as a DG419or one-third of a CD4053—to combinean analog signal with a standard PWMsignal. Most microcontrollers can easilygenerate the PWM signal.

In many embedded communications and networking applications it is oftennecessary to derive fractional frequencies from some common baselinefor use in particular applications. In communications ...
