Hi,
Firstly, i would like to know how could i set up a circuit to test for the input offset voltage ?
Because for TL071 Op amp, i saw a parameter measure information which shows a input offset-voltage null circuit. Can i use a function generator to generate a square wave of +- 10v at the V- and ground V+ and using oscilloscope to Vout to see if there is any deviation from the reference point of 0v? The supply voltage into the Op amp is +- 10V .
Secondly, i understand there is a integration constant (c) in an integrator. How can we get the value of the integration constant ? Do we do a setup as similar on on how i test for input offset voltage and check the t=0 value ?
Third, is there a way using theortical method to check on the frequency that will cause the op amp to be saturated ? Or i've to manually adjust the input signal from the function generator to visually look if the output is being saturated.
Lastly, is there really a different if we have the integrator circuit to have its capacitor being charged up before giving an input signal ? I can switch because i've attached an multiplexer to allow me to switch between charging up the capacitor and doing integration.
Really appreciate for your help.
