| description | A novel inverter-based digital floating-gate MOSFET sensor design for commercial X-ray dosimetry is presented. The biomedical healthcare industry sterilizes blood products for storage purposes using Gamma and X-ray radiations. This requires an ultra-low-power dosimeter that ensures irradiation does not exceed the maximum allowable 50 Gy while providing the required minimum levels of 25 Gy. In this work, minimum-sized MOS transistor devices are employed in an inverter configuration, eliminating the continuous flow of current and reducing power consumption significantly. Maximum measured currents, which flow only during the transition period, are in the nA range, compared to continuous currents of conventional sensor designs in the μA range. Final measured results show the viability of the proposed design for radiation dosimetry applications. |
