A Fully Integrated Hall Sensor Microsystem for Contactless Current Measurement

Maher Kayal, Marc Pastre, Andrea Ajbl

Contactless current measurement based on Hall-effect sensors can be performed in either closed-or open-loop configuration. In this paper an open-loop sensor system with a current-mode output is described. The system measures the magnetic field induced arou ...

A current-mode back-end for a sensor microsystem

Maher Kayal, Marc Pastre, Andrea Ajbl

is paper presents a voltage-to-current converter as a current-mode output buffering stage for sensor interfaces. The converter can be used in any microsystem needing a current output. It is presented here in the context of a Hall sensor microsystem. The sy ...

Inversion factor based design methodology using the EKV MOS model

Maher Kayal, Marc Pastre, Andrea Ajbl

This paper presents a hierarchical design methodology based on the inversion factor (IF) as a key design parameter and the equations of the EKV MOS Model. A structured design approach is used to allow high flexibility. The efficiency of the methodology is ...
