Introduction In our previous article about the Integrator op-amp, we have seen that the implementation of a reactive component significantly changes the electrical behavior of OPAMPs in comparison to fully-based resistive designs. Indeed, the presence of a capacitor in the feedback loop constitutes the main aspect of integrators, which perform electrically the mathematical operation of […]

Introduction In the previous tutorial concerning AC resistance, we have seen that the behavior of a resistor is the same in DC or AC regime under normal frequencies. However, other basic electrical components such the inductor, strongly depends on the frequency of the AC signal. A presentation of the concept of inductance is given in […]
