▣ Abstract :Smart sensors for IoT devices are systems in which sensors and dedicated interface electronics are integrated on the same chip. Due to the low-level analog output of typical sensors, designing interface electronics is quite challenging, whose inherent precision is limited by 1/f noise and component mismatch. However, since most sensors are quite slow compared to transistors, dynamic techniques, such as auto-zeroing, correlated double sampling, chopping, and sigma-delta modulation, can often be used for higher precision. This talk describes such techniques in the design and realization of state-of-the-art CMOS smart sensors.
