Pulse-width modulation (PWM) peripherals have enjoyed a long association with microcontrollers and power control, starting with motor control and power conversion. For the most part, these ...

Many embedded-microcontroller applications require generation of analog signals. An integrated or stand-alone DAC fills the role. However, you can often use PWM signals for generating the required ...

voltage. Often a passive single-pole RC filter will satisfy design requirements, but this approach typically suffers from several drawbacks including slow response time, noisy results, and having an ...

A few weeks ago, I saw a reader’s question about how to run PS3 cooling fans using an external electronics circuit. At the time I was busy with some other projects. The other day, I decided to put my ...
