If the ramp driving your PWM-based controller isn't linear or monotonic, or just plain noisy, your DC/DC converter isn't going to work up to its capabilities. Here's what you need to know to get the ...

It’s not always easy to design a ramp generator whose ramping frequency can be changed without manipulation of capacitors or inductors. Many ramp circuit designs are available, but they may not be ...

Why PWM? Switch-mode converters employ a power semiconductor switch (usually a MOSFET) to drive a magnetic element (transformer or inductor) whose rectified output produces a dc voltage. Efficiencies ...

Logic Noise is all about using logic circuits to make sounds. Preferably sound that will be enjoyable to hear and useful for making music. This week, we’ll be scratching the surface of one of my ...
