Operational Amplifier Gain-Bandwidth Characteristics
Operational Amplifier Gain-Bandwidth Characteristics
This Demonstration investigates the gain-bandwidth properties of a basic inverting amplifier based on an LM741 operational amplifier. You can toggle the display to show a schematic of the amplifier circuit and a Bode plot displaying its gain-bandwidth properties. This simple amplifier circuit exhibits characteristic roll-off of the gain; that is, the actual gain of the circuit drops below the nominal gain as the frequency of the signal increases. The slew rate describes the time rate of change of the potential at a circuit node.
