| Summary: | The space environment can cause severe problems for electronic circuits. The plasma, radiation, debris, and no thermal convection are some space environment-specific conditions. Space radiations are the source of several damages, such as total ionizing dose (TID). During a satellite’s mission life, the TID gradually degrades the quality of the electronic components. Designing reliable equipment requires enough information about the mission environment. Some part of this information could be obtained employing dosimetry. There are several dosimeters based on the type and intensity of radiation sources. In the present work, a dosimeter has been introduced that could measure the TID for a satellite in a low earth orbit. This dosimeter uses a RadFET to measure the TID. The simulation results and implemented version of the dosimeter verify the accuracy and quality of the proposed dosimeter. The low power consumption, fast data recording, and thermal stability are some of the features of the proposed dosimeter |
