Radiation tolerant, thin, passive CMOS sensors read out with the RD53A chip

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...

Differential read-out circuit for capacitive sensors

MEMS Pressure Sensor With Two Thin Film Piezoelectric Read-Out

We propose the structure to have only two pares of PZT thin films on the basis of [11]. This causes the structure to become simpler and easier to fabricate. And except its first vibration mode that is also the base mode, the other modes have no effect on the acceleration measurement. So it can be a better choice for the measurement of acceleration and it can have a huge potential as a micro-sen...

CMOS compatible optical sensors with thin film interference filters

Optical microsystems with high spectral selectivity and fabrication compatible with a standard CMOS process have been realized. PN junction photodiodes are used for photodetection. A multi-layer optical filter fabricated on top of the active photodiode forms a Fabry-Perot optical resonance cavity. The resonance wavelength can be designed within the entire visible spectrum. The filters are fabri...

Read Noise Distribution Modeling for CMOS Image Sensors

Abstract—We report on an empirical model that describes the read noise statistics in CMOS image sensors. This model includes pixel-to-pixel variations in thermal, 1/f and RTS noise. It is based on the “unlucky pixel” concept where the sourcefollower FET channel is dominated by a single sub-channel and that RTS is due to the interactions of uniformly-distributed defects to this. In addition, we ...
