Resumen
In this paper we present a new dosimeter based on a pair of thick gate oxide MOSFET sensors. A differential circuit topology with a feedback loop provides stabilized output with selectable sensitivity amplification for real time in vivo dosimetry. Radiation response shows a wide linear output range and an effective thermal rejection. These properties make this circuit suitable for dose control in radiotherapy applications.
