Gain peaking effect
WebResonant peaking occurs at around 2.5 MHz due to the inductance of the bead and the 10 nF ceramic capacitor. Instead of attenuating the fundamental ripple frequency at 2.4 MHz, a gain of 10 dB occurs. Other factors that have an effect on the resonant peaks are the series and load impedances of the ferrite bead filter. Webbecomes unstable and the output oscillates indefinitely at the frequency where the gain = 1 and phase margin is 0°. In a circuit with a positive phase margin, the oscillations decay …
