Abstract
An electric-field capacitive coupler module includes a first processing unit, a first communication interface coupled to the first processing unit, a second communication interface, and an electric-field capacitive coupler that defines an isolation barrier. The electric-field capacitive coupler apparatus is coupled between the first communication interface and the second communication interface.
Claims11
An electric-field capacitive coupler module, comprising:
- a first processing unit;
- a first communication interface coupled to the first processing unit;
- a second communication interface;
- and
- an electric-field capacitive coupler apparatus, embedded in a multi-layer printed circuit board (PCB), that defines an isolation barrier coupled between the first communication interface and the second communication interface, the electric-field capacitive coupler apparatus including a first portion configured to electrically-coupled to a receiver and a second portion configured to electrically-coupled to a driver, the first portion including a first electrically-conductive plate disposed on a first layer of the PCB and a second electrically-conductive plate disposed on a second layer of the PCB.
