Abstract :
Contactless interconnection methods are studied as possible alternatives for galvanic interconnection in mobile devices. This is due to ever-increasing requirements for the connector size and bandwidth. Capacitively coupled interconnection is implemented on a PCB level and signal transmission with pulse signaling is demonstrated for 1 MHz, 10 MHz and 40 MHz PRBS signals. Different schemes for signal transmission through a capacitive interconnection are discussed and their potential benefits are evaluated.
