About John Penton Expertise I am happy to answer questions on semiconductor devices - in particular high-voltage devices.
Also any electronics or physics homework questions.
I`m not a semiconductors professional (at the moment), so no really in-depth questions please.
Experience Degree level education in Natural Sciences and Electrical and Information Sciences.
My final-year project was in high-voltage power MOSFETs.
Currently work for ARM Ltd, designing microprocessors.
Question I have done an experiment with the Operational Amplifiers as the Integrators and Differentiators. I used the sine wave in both and I plotted the Vout/Vin against frequency (freq in log scale)
I am supposed to draw conclusions from it but I haven;t got a clue ... My problem is that I really don;t know how the operational amplifier used as integrator and differentiatior treats the sine wave...
Thanks a lot for your answer.
Answer The circuits are called integrators and differentiators because of their relation to basic calculus.
Write yourself an expression for your input sine wave (eg. V = Vo sin (wt)) and then integrate it and differentiate it with respect to t. Divide each by your original expression to give you Vout/Vin in each case. Does the result bear any resemblance to your graph? Draw your conclusions.
