Fig. 1. Bode plot of a DC/DC converter. The phase margin of this converter is indicated as a very respectable 78 degrees and the gain margin, indicates a less than stellar, but acceptable 6.7 dB.

With the equation defined, ADS allows us to plot the extracted loop gain as “T” (green waveform) representing the Bode plot ().We also simulated the bode plot using traditional methods and ...

Electrical engineers will recognize the Bode plot as a plot of the frequency response of a system. It displays the frequency on the x-axis and the phase (in degrees) or magnitude (in dB) on the y-a… ...

This calculates as a gain of -3.01 dB. The voltage across C1 is phase-shifted 90° from the voltage across R1. Since the real and imaginary voltage components are equal, it gives a phase-shift through ...
