A temperature and supply voltage compensated floating-gate MOSFET dosimeter is presented. The dosimeter consists of two pairs of floating-gate sensor transistors with identical geometry for compensation purpose, V_TH (threshold voltage) extractor circuits and substractors. The dosimeter output presents the threshold voltage changes of the floating-gate MOSFET sensors before and after radiation. The circuit has been modeled and simulated in Hspice using TSMC 0.35?m CMOS technology at 2.4V power supply. Simulated results show a low sensitivity to temperature and V_DD variations and a low power consumption of 0.44mW.
