Design and Characterization of a Data Converter in a SiC CMOS Technology for Harsh Environment Sensing Applications

This work presents the design and characterization of an analog-to-digital converter (ADC) with silicon carbide (SiC) for sensing applications in harsh environments. The SiC-based ADC is implemented with the state-of-the-art low-voltage SiC complementary-metal-oxide-semiconductor (CMOS) technology developed by Fraunhofer IISB. Two types of...

Visible Blind Quadrant Sun Position Sensor in a Silicon Carbide Technology

In this paper, we present a quadrant sun position sensor microsystem device in a silicon carbide technology that operates in a field-of-view of ±33° and reaches a mean error of 1.9° in this range. This will allow, for the first time, an inherently visible blind sun position sensor in a CMOS compatible technology. Opto-electronic integration of...

Resistive and CTAT Temperature Sensors in a Silicon Carbide CMOS Technology

Accurately sensing the temperature in silicon carbide (power) devices is of great importance to their reliable operation. Here, temperature sensors by resistive and CMOS structures are fabricated and characterized in an open silicon carbide CMOS technology. Over a range of 25-200°C, doped design layers have negative temperature coefficients of...
