چکیده
A CMOS bandgap current reference circuit has been developed in a 0.13 um CMOS technology. The circuit exhibits low sensitivity to temperatureand power supply variations. The combination of the natural properties of thin gate oxide MOS transistors with a gate-all-around layout approach makes stable operation in harsh radiation environment possible. In the present design we utilize only MOS structures and poly-silicon resistors. The output current varies in the range 0.9 % when the circuit is being irradiated up to a 200 Mrad.
