▣ 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.
