Claim:
1. An implantable electronic device, the device comprising: a housing; at least one connector coupled to the housing and configured to at least one of receive first electrical signals or transmit second electfical signals; and an integrated circuit disposed within the housing, wherein the integrated circuit comprises a first clamp stage coupled to a first supply voltage line of a first voltage domain of the integrated circuit and a second clamp stage different than the first clamp stage, wherein the first clamp stage is configured to dissipate magnetic resonance imaging (MRI) induced energy from the first supply voltage line in response to at least one of a voltage or a current on the first supply voltage line exceeding a respective predetermined voltage threshold value or a current threshold value, and wherein the first clamp stage is configured to be coupled to the first supply voltage line and the second clamp stage is configured to be coupled to a second supply voltage line of a second voltage domain.
