Hi, I have looked at the diagrams. Still at bit unsure... where/how would i add the gain to the diagram? ad what other values would i need to add to the diagram?
For example if you want a gain of -50 you must put one resirtor for example 1K
and the other will be 50K.
Never put low values on the resistor keep upper than 1K.
depending of the opamp you can use tha gai of 50 until the frequancy given by
Fmax = Funi/Av
That Funi is the frequency that the ampop has the unir«t gain and depends of the device.
Av is the gain that you define for the circuit.
Fmax is the max frequency that you can inject without any attenuation of the gain inicialy defined.
In upper frequency tha gain will be lower.
The solution is use a better frequency response opamp or use for example two opamp defined an 7.07 gain in each. 7*7 aprox 50
Is this solution the max frequency will be higher.
Fmax= Funi/Av If Av lower then Fmax is Higher.
Just use the more adquated solution or an combination of several.
