Assignee: APPLE INC.
Field: Basic communication processes (Electrical engineering)
Classification: CPC H | IPC H

Claim 13:
14. An electronic device, comprising:
a first integrated circuit comprising a receiver, the receiver comprising a first unit gain buffer configured to receive a reference voltage signal;
a second integrated circuit comprising a transmitter, the transmitter comprising
a power supply,
a second unit gain buffer configured to receive the reference voltage signal from the first unit gain buffer,
an amplifier coupled to the second unit gain buffer and configured to receive a power supply signal from the power supply, and
an offset tracker coupled to the amplifier and configured to compensate for a direct current voltage offset caused by at least a variation in the power supply signal; and

a connector coupling the first integrated circuit to the second integrated circuit, the second unit gain buffer configured to receive the reference voltage signal from the first integrated circuit via the connector.
