Radiation-Hardened ICs for Implantable Medical Devices

Radiation hardened integrated circuits for implantable medical devices

Lately I’ve received many inquiries about the paper on radiation-hardness testing of implantable integrated circuits that I published with Dr. Larry Stotts (now Executive VP R&D at Biotronik), and the late Dr. John Prince.  This is because the effects of medical diagnostic and therapeutic radiation are becoming an issue of concern to physicians who often encounter the need for radiotherapy in the growing population of patients implanted with pacemakers, defibrillators, neural stimulators, and drug-delivery pumps.

Although the paper reported mainly on the test of floating-gate EEPROMs, the modern interest is on the test methods that we developed to test ICs used in implantable devices for hardness to the type of radiation encountered in the medical field.
