The standard integrator using an ideal op-amp is given in Figure 6.5. The function of an
integrator is to perform mathematical integration upon the input. A square wave, when
integrated, will become triangular. A triangular wave, when integrated, will become a parabolic
waveform, which is close to a sine wave.
A practical op-amp at low frequencies has small DC off-set voltages and currents, which can
sometimes create havoc with the output of an integrator circuit. The integrator may saturate and
the output voltage becomes pegged at either the positive or negative saturation level. This
problem is not noticeable in our lab
