But they also have multiple contributors to their reactance. For example, a capacitor has a series inductance that becomes more apparent at high frequencies. When we measure a real capacitor, the equivalent series inductance (ESL) will impact the capacitance reading, but we won''t be able to measure it as a separate, distinct component.
This method has been implemented in [31] using an active De-Sauty bridge, in which the automatic gain control is composed of a reference capacitor, a phase-sensitive detector (PSD), an ADC/DAC unit, and an analog multiplier. This implementation reported accuracy of 0.1 pF over a 142 pF range, hence a dynamic range of 63.04 dB. The stray …
To measure the capacity and the internal resistance accurate, the measure frequency must be chosen so that the reactance and resistance are approximately the same.
