operational amplifier - Op-amp differentiator and integrator circuit: resistor and capacitor values


I don't understand how to determine value of resistors and capacitor in differentiator and integrator circuit of Op-Amp.


I tried to align the amplitudes of these sine waves. I keep changing their values but I can't get it right.


The best result I can get:


differentiator results


The circuit:


differentiator circuit


Okay, so that is my question about the differentiator circuit. The next question is about my integrator circuit. As with the differentiator, I don't understand how these resistors and capacitors affect each other. I tried to make the source a triangular wave and the result a sine wave. Alas, no luck.


Here is the result:



triangular result


Here is the circuit:

The next one is a square wave. I managed to get it to square wave, but the result is supposed to be a triangular wave and all I get looks like a straight line.


Here is the result:


Square result


Here is the circuit:


Square circuit


How can I determine the correct resistor and capacitor values?

arduino - Can I use TI's cc2541 BLE as micro controller to perform operations/ processing instead of ATmega328P AU to save cost?

I am using arduino pro mini (which contains Atmega328p AU ) along with cc2541(HM-10) to process and transfer data over BLE to smartphone. I...
