Abstract
A method and class of circuit configurations for coupling low-frequency signals from one stage of an electronic apparatus to another stage, from the outside world to such a stage, or from such a stage to the outside world, through the use of a plurality of symmetrical double-layer capacitors combined with other electronic components are disclosed. The capacitors are used for signal transmission while blocking direct current, rather than for energy storage. Use of double-layer capacitors in place of more conventional capacitors permits the transmission of a much wider range of signals with far less distortion. The technology is particularly well-adapted to use in medical devices, including bioelectronic stimulators, where redundant devices are required for safety in case of single component failure while unacceptable levels of distortion may occur when conventional components are used.
