Abstract:
Coupled resonators for galvanically isolated signaling between integrated circuit modules. An illustrative multi-module integrated circuit comprises: a transmitter in a first module, the transmitter providing a modulated carrier signal; a receiver in a second module demodulating the modulated carrier signal; and a galvanically isolated signaling path that includes: a first integrated resonator in the first module and a second integrated resonator in the second module, the first and second integrated resonators being resonantly coupled to convey the modulated carrier signal from the transmitter to the receiver. An illustrative embodiment of a method for providing an integrated circuit with a connection terminal for galvanically isolated signaling comprises: equipping the integrated circuit with a transmitter or receiver of a modulated carrier signal; connecting a transfer conductor to the connection terminal; and resonantly coupling the transmitter or receiver to a transfer conductor to convey the modulated carrier signal between the transfer conductor and the transmitter or receiver.
