Abstract :
A novel fully integrated MOSFET radiation dosimeter consisting of two pairs of floating-gate sensor transistors with identical geometry and two VTH (threshold voltage) extractor circuits for the sensor transistors respectively is presented. The dosimeter output is the difference of the output of the two VTH extractor circuits, which presents the difference of the threshold voltage of the floating gate MOSFET sensors before and after radiation. The VTH extractor circuit has been simulated in Hspice using TSMC 0.35 μm CMOS technology at 2.9 V power supply. Simulated results show insensitivity to VDD variation and low power consumption of 0.44 mW.
