Electronic devices become smaller with increasing efficiency demands. The power density as well as the switching frequency tend to increase, adding additional complexity to the system. Multiple supply voltage levels with fast recovery speed require highly dynamic control systems. To ensure the stability of voltage regulators and switched mode power supplies the control loop behavior needs to be characterized not only in simulation but also in real life measurements. In this webinar we share our knowledge on accurate loop stability measurements and demonstrate live measurements using the Bode 100.
