High-capacity, multilayer ceramic capacitors (MLCC) have a property often not well understood by electronic designers: the capacitance of these devices varies with applied DC voltage. This phenomenon ...

You need to know how to measure the current that flows through a component in a circuit and the voltage across it. The ammeter must be connected in series with the component – remember, in a series ...

As the primary switching device used in a broad range of power conversion applications, MOSFETs play a central role in power supply design. Defining their performance characteristics is crucial to ...

The voltmeter is connected in parallel with the component. The supply voltage is shared between components in a series circuit, so the sum of the voltages across all of the components in a series ...

Digital multimeters (DMM), once called voltmeters, have been described as the tape measure for engineers in the new millennium. With electronics and electrical circuits included in almost every ...

The article discusses key lab techniques for evaluating switch-mode power supplies (SMPS) and how to accurately measure voltage ripple and switch node using the right oscilloscope probes and methods.
