I set up a non inverting closed loop opamp with 100 gain to a function generator, set to produce a 10mV sinusoid @ 1khz. The graph of Vin vs Vout (oscilloscope) is kinda like a very thin parallelogram. Theres a small phase shift. Does anyone know why this is? Ideally one value of Vout produces one value of Vin, but what is the cause of this systematic error?
