Abstract :
This paper presents a charge pump voltage doubler for programming flash memories to be employed in space applications. The device has been designed in a commercial 180 nm CMOS technology using radiation hardening by design techniques. Radiation tests carried out on prototype samples demonstrate immunity to latch-up, and an adequate level of hardness with respect to total dose.
