Abstract

A device and system for monitoring ionizing radiation. The device including: a diode formed in a silicon layer below an oxide layer buried below a surface of a silicon substrate; and a cathode of the diode coupled to a precharged node of a clocked logic circuit, an output state of the clocked logic circuit responsive a change in state of the precharged node, a state of the precharged node responsive to ionizing radiation induced charge collected by a depletion region of the diode and collected in the cathode.
