A second-order sigma-delta (ΣΔ) modulator for high-temperature (HT) applications is presented. The modulator exploits the advantages of the fully-depleted (FD) SOI CMOS technology as well as a dedicated design procedure in order to extend the temperature range of classical architectures up to 300°C, thereby avoiding compensation circuits which add to the power dissipation
