Optimum Design Rules for CMOS Hall Sensors

This manuscript analyzes the effects of design parameters, such as aspect ratio, doping concentration and bias, on the performance of a general CMOS Hall sensor, with insight on current-related sensitivity, power consumption, and bandwidth. The article focuses on rectangular-shaped Hall probes since this is the most general geometry leading to shape-independent results. The devices are analyzed...

An Immunoassay Platform Based on CMOS Hall Sensors

We describe an immunoassay utilizing standard CMOS technology. An array of Hall sensors is used to detect the magnetic beads that serve as the assay signal. Electrical and magnetic modulation is employed to improve the sensitivity of the sensors. The devices receive two post-processing steps to improve sensitivity and biocompatibility. We have fabricated prototype devices using a 0.25-μm BiCMOS...

Design rules for robust capacitive sensors

Capacitive technologies play an increasingly important role in the fields of industrial and automotive sensors. The noncontact working principle, on the one hand, is the main advantage of this technology; on the other hand, the sensor is thus sensitive to electromagnetic disturbances. This paper describes methods to successfully develop capacitive sensors, which can reliably be operated in hars...

Neural Monitoring With CMOS Image Sensors

Implantable image sensors have several biomedical applications due to their miniature size, light weight, and low power consumption achieved through sub-micron standard CMOS (Complementary Metal Oxide Semiconductor) technologies. The main applications are in specific cell labeling, neural activity detection, and biomedical imaging. In this paper the recent research studies on implantable CMOS i...
