Switching regulator bode plot

SpletThe plot shows that Vin has a constant value of 1 volt at all frequencies, while Vout quickly falls to-wards zero at high frequencies. A standard representation used in electronics is the Bode plot, which has logarithmic amplitude and frequency axes, so right-click on the frequency axis to make it logarithmic. Splet02. sep. 2024 · Bode plots and power supplies. A Bode plot represents the gain and phase of a feedback system as a function of frequency. It was developed by Hendrik Wade …
