-This study focused on the design and characterization of a Temperature Sensor with an 8-bit Low-Voltage Incremental Delta-Sigma Analog-to-Digital Converter (ADC). The Proportional to Absolute Temperature (PTAT) part of an All-MOS bandgap voltage reference was utilized as the Temperature Sensor. The design was implemented using 0.18um CMOS Technology. The temperature sensor and voltage reference operates using the typical supply voltage of 2.5V while the ADC part operates on a low voltage 1-Volt supply. The circuit design can operate from 0ºC to 85ºC with a temperature coefficient of 0.933mV/ºC or 2.5LSB/ºC and was implemented and simulated using Synopsys Tools.
