When voltage is applied to a capacitor, a charging current will flow; this current will delay the buildup of the full applied voltage generating a time displacement of the alternating voltage behind the current. In a "no-loss" perfect capacitor, the phase difference between voltage and current would be exactly 90°. In a real
I''ve only used DC forward terminations when the driver can handle the power, and back-terminations when the driver was low power. If I were going to try to use an AC forward termination with a low-power driver, I''d be worried about the complex nature of the termination vs. the real ##Z_0## of the TL.
Dielectric formulations and chip capacitors are often tested for reliability under voltage and temperature for specified time periods, a process referred to as burn-in or voltage conditioning. The specifications applicable to burn-in of multilayer ceramic capacitors (MLCCs) are MIL-C-55681, MIL-C-123 and MIL-C-49467.
to generate the appropriate termination offset voltage and is a widely used termination approach for 3.3V LVPECL drivers. The disadvantage to this architecture is that the Thevenin transformation results in requiring two 1% resistors, 82.5 and 127 Ohms for each termination. 82 and 130 Ohms 5% resistors are therefore more commonly

In this study, it is shown that since the distance of two adjacent inner electrodes of multilayer ceramic capacitors (MLCC) with high capacitance is close enough, the termination of the MLCCs can be made by direct plated Ni termination instead of by the existing dipped and cured Cu termination. The characteristics of termination MLCC made by direct nickel plating …
Yes, capacitors exist, but all capacitors are non-ideal, and it is this deviation from a theoretical capacitance that determines how to impedance match a load that exhibits capacitive behavior. Let''s take a look at this important aspect of interconnect design and see what it really means to terminate a capacitive load.
