How to measure capacity versus bias voltage on MLCCs

January 20, 2015 // By Fons Janssen, Maxim Integrated
The capacitance of multilayer ceramic capacitors (MLCCs) varies with applied DC voltage, to an extent that can vary considerably from one type to another. This article presents a methodology and a circuit to measure the change in capacitance, and contains measurement data to validate the approach taken.
