An Integrated Thermopile-Based Sensor with a Chopper-Stabilized Interface Circuit for Presence Detection

This paper presents a sensor-readout circuit system suitable for presence detection. The sensor consists of a miniaturized polysilicon thermopile, realized employing MEMS micromachining by STMicroelectronics, featuring a responsivity value equal to 180 V/W, with 13 ms response time. The readout circ...
