High-frequency capacitive wireless power transfer technologies
The technical maturity of high-frequency capacitive wireless power transfer (CWPT) technologies has reached a point where they can be industrially introduced on a large scale. This paper will present the trends and the chronological efforts to improve and enhance CWPT technologies that are currently gaining interest and spotlight. …
Hardware and Systems Engineering Design
Created:11/05/2020 Last Updated: 7/06/2023 Introduction In high-speed differential pairs, AC coupling capacitors are commonly used to pass AC signals while blocking DC signals. These capacitors, also known as AC coupling or DC blocking capacitors, prevent common mode voltage or DC bias from
Coupling & Bypass Capacitors
2.0 - Coupling Capacitors The purpose of a coupling cap is to pass the wanted audio (AC) signal, while blocking any DC from preceding stages or source components. DC will cause pots to become noisy (scratching noises when operate), and cause relatively loud clicks when (if) muting relays or similar are used.
7.6: Multi-Stage Amplifiers
7.6.1: Direct Coupling With a little creativity, it is possible to create multi-stage designs that use fewer components but which achieve higher performance. One technique is to employ direct coupling of the stages. Direct coupling allows DC to flow from stage to ...
