Abstract
According to one embodiment, there is provided a high voltage isolation dual capacitor communication system comprising communication drive and sense electrodes and corresponding first and second capacitors that are formed in two separate devices. The two devices are electrically connected in series to provide a single galvanically-isolated communication system that exhibits high breakdown voltage performance in combination with good signal coupling. The system effects communications between drive and receive circuits through the first and second capacitors, and in a preferred embodiment is capable of effecting relatively high-speed digital communications. The system may be formed in a small package using, by way of example, CMOS or other semiconductor fabrication and packaging processes.
