In this work, an integrated digital thermometer was designed at transistor level in 0.18 m BiCMOS SiGe technology for a temperature range of -50 C to 130 C. The 1 accuracy achieved at 100 C is 1.21 C. The digital thermometer consists of temperature sensor, Instrumentation amplifier (pre-amplifier), Sample-and-Hold, Comparator, Successive Approximation Register (SAR) and Digital-to-Analog Converter (DAC). The ADC designed is a successive approximation register (SAR) ADC having a sampling rate of 5 kS/s at 3V. The main thrust of this work was to have a minimum error. As the major error source...
