GALVANIC ISOLATOR
First Claim
1. A galvanic isolator comprising:
- a split circuit element having first and second portions;
a substrate comprising an insulating polymeric or polymeric/inorganic layer having first and second surfaces, said first portion and said second portion being disposed on said substrate;
a transmitter that receives an input signal and couples a signal derived from said input signal to said first portion; and
a receiver connected to said second portion that generates an output signal that is coupled to an external circuit;
wherein said first portion is disposed on said first surface and second portion being disposed on said second surface;
wherein said split circuit element comprises a capacitor having a first plate comprising said first portion and a second plate comprising said second portion.

Abstract
A galvanic isolator having a split circuit element, a polymeric substrate, a transmitter and receiver is disclosed. The split circuit element has first and second portions, the first portion being disposed on a first surface of the substrate and the second portion being disposed a second surface of the substrate. The transmitter receives an input signal and couples a signal derived from the input signal to the first portion. The receiver is connected to the second portion of the circuit element and generates an output signal that is coupled to an external circuit. The galvanic isolator can be economically fabricated on conventional printed circuit board substrates and flexible circuit substrates.
