http://ecircuitcenter.com/Circuits/op_bandwidth1/op_bandwidth1.htm WebThe op-amp has a bandwidth of f C. With negative feedback, its closed-loop bandwidth expands to f CL. f CL is calculated as follows from the gain-bandwidth product equation: f CL = f T / A CL When the closed-loop gain (G CL) or the bandwidth (f CL) is insufficient, it is necessary to select an op-amp with high f T.
