Total Ionizing Dose Tolerance Estimation for an All-MOS Temperature-Insensitive Voltage Divider

We propose a total ionizing dose tolerance estimation of a previously presented all-MOS voltage divider that can be used in space-bourne and high-energy physics equipment working in harsh environment. The proposed circuit works well in both MOSFET weak and strong inversion modes. The estimations are made by means of SPICE simulation with threshold voltage changes according to available theoretical and experimental data.
