Abstract
An RFID tag for use with an MRI machine has an integrated circuit and structure for protecting it from damage when exposed to an intense MRI RF transmitter field. The structure for protecting the integrated circuit may include a controllable low impedance device coupled across the integrated circuit, a controllable high impedance device coupled in series with the integrated circuit, and/or frequency selective RF filter.
