One of the greatest challenges in designing switching power supplies is limiting its Electromagnetic Interference (EMI) with other electronics. Beyond layout techniques to minimize high di/dt current ...
Since the late 1970s, designers have successfully improved the effective resolution and spurious performance of A/D converters by adding dither—uncorrelated noise—to a converter's input and then using ...
When working with mixed-signal technology, you will find that the subject of dithering keeps showing up. Most engineers know that averaging “n” samples of an analog-to-digital converter (ADC) will ...
Fig 1. In a typical PWM controller in which the active devices are driven by a simple square wave, a Fourier representation of the clock’s frequency spectrum consists of the fundamental switching ...
EMI design:All relevant devices must pass EMC standards, but it can be challenging to optimize devices for EMI performance. Flyback solutions typically require a common-mode (CM) inductor to improve ...
