In this configuration, the output treats the feedback resistor as an additional load parallel to the 100 Ω load used for testing.
In order to obtain the maximum flat second-order Butterworth frequency response,
IEQ=Equivalent input noise current when the output noise bandwidth is limited to F<1/(2 π RFCD).
Putting high resistance values into formula 2 can quickly control the total equivalent input reference noise.
Capacitive load is one of the most demanding but common load conditions for operational amplifiers.
nerally speaking, before the fundamental wave reaches a very high frequency or power,
