Where is the design gain of the amplifier, is the frequency of a sinusoidal input waveform, and is a constant. We used a value of 700,000 (V/V) Hz for the gain-bandwidth product of the amplifier based on fitting the three datasets shown in the plot to a gain-frequency relationship of the form Analyses of the basic inverting op-amp amplifier typically assume that it is characterized by a constant gain-bandwidth product. the maximum peak-to-peak input voltage of a sinusoidal waveform with 0 DC offset that would not be distorted due to the slew rate and output voltage swing limitations of the LM741Ī.the frequency,, of the dB roll-off position for the selected design gain.the gain that the circuit actually delivers with the selected design gain and for a sinusoidal input waveform with the selected frequency and obeying the slew rate and output voltage swing limitations.a vertical black line that marks the limit of the bandwidth of the amplifier by its intersection with the dB roll-off position of the gain curve for the selected design gain.three dotted lines that show actual data for circuits with design gains of approximately 3, 10, and 30.a shaded region that represents the bandwidth of the amplifier for the selected design gain.a solid line displaying a model of the entire gain curve of the circuit as a function of frequency, as presented in note A below, for the selected design gain and an input sinusoidal waveform.a single black point that corresponds to the gain of the circuit for the selected design gain and an input sinusoidal waveform of the selected frequency.

The information displayed in the Bode plot includes: The bandwidth of the amplifier is the range of frequencies for which the circuit gain is within 3 dB of the design gain. The Bode plot displays the gain in decibels: on the vertical axis versus the logarithm of the frequency on the horizontal axis.
