THERMIC: a Hardened Temperature Controller for Regenerating CMOS Circuits Exposed to Ionizing Radiation

A Radiation hardened temperature controller intended to regenerate CMOS circuits has been designed using commercial off-the-shelf components. Tested with
⁶⁰
Co gamma rays, it has shown a radiation hardness greater than 65 kGy. The hardening methodology used to design the temperature controller is validated through these results.
