A Fully Integrated Hall Sensor Microsystem for Contactless Current Measurement

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 ...

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 ...
