While using a digital multimeter to diagnose electrical problems on customers’ equipment, I frequently hear the comment, “I’ve got one of those multimeter things, but I never learned how to use it.” ...

Alternating current (ac) or direct current (dc) circuits are capable of carrying very different currents, as illustrated by the ratings on the switch in Figure 1. This is why it’s so important for ...

How can you take the dc bias effect of multi-layer ceramic capacitors into account in circuit simulations? One way is to leverage LTspice’s nonlinear capacitor capabilities and a reasonable model.
