We're here to settle, once and for all, the pros and cons of spread-spectrum clocking as an EMI countermeasure. In case you're unaware, many systems today employ frequency-modulation of their clock ...
Most designers are familiar with the technique of using a spread-spectrum clock to reduce apparent EMI/RFI emissions. By deliberately dithering the system clock, the radiated energy is spread across ...
Ways to mitigate noise in SMPS. What to look for in PCB layout to reduce EMI. What are SSFD and DRSS? Electromagnetic-interference (EMI) reduction techniques for power circuit designs are segmented ...
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 ...
The Internet, as we know it today, is still mostly an information highway. However, even as we speak, more and more once autonomous, physical objects are becoming intelligent. That includes the ...
