To obtain the frequency response of a circuit, or its Bode plot, using LTspice, it helps to start with a simple circuit example. Figure 1 shows a second-order low-pass filter. The input and output ...

Figure 2 shows the gain curve for the control loop in a Bode plot. It yields two important pieces of information. The frequency at which the gain is equal to 1—that is, at 0 dB—can be read ...

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, … ...

It should be noted that Aol and β are functions of frequency. The results of this relationship are seen in the Bode plot as shown in Figure 2 (Note: Aol is shown in blue, 1/β is shown in orange).

AC parameters which describe the amplifier's performance over frequency can appear very confusing. One tool used in many descriptions and analysis is the Bode plot, Reference 1. This graphical ...

I am getting rather pissed off at Excel. I keep trying to make a Bode plot with the X-axis being 5 Cycle semi-log (just a log10 axis would be alright too) and the Y-axis linear. I cannot find an ...

The Bode plot shown above in Fig. 6 has a phase margin of 46 degrees at a crossover frequency of 3.92MHz. The minimum distance from (1,0) occurs at 5.50MHz with a phase of 34 degrees.

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, but making ...
