Bode plots – or frequency response graphs – are found in just about every piece of literature for high-end audio equipment. It’s a simple idea, graphing frequency over amplitude, … ...

Figure 1. Example of a circuit for a second-order low-pass filter. The circuit will be stimulated with a sine wave. This requires an AC sweep, which can be found under the AC Analysis tab in the menu ...

This is great, but there is a SPICE booby trap waiting for the unwary user of the Bode plotter. Please consider this zero-frequency IF circuit from my Living Analog blog entitled, Zero frequency IF.

In Table 3, there is around 10 deg. of difference between Bode plots and output impedance because of the implementation of the ripple-injection circuit in IC-HM. In the Bode-plot measurements ...

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… ...

The Bode plot is shown in Fig 5b. The slow-lane loop gain starts with a -1 slope because of the origin pole formed by R upper = R 12 + R 10 , C zero = C 6 . The power stage's pole, f p , is about 20 ...

Bode plot showing BW, phase, and gain margins and the crossover frequency (Fc) at 0 dB. ... A simplified model circuit for a VM buck LC filter behavior. Analog Devices. 4.
