Tunable floating active inductor with internal offset reduction

Maher Kayal, Sidi-Rachid Cherkaoui, François Krummenacher, Marc Pastre, Laurent Fabre, Ira Nagel

Presented is a transistor-level implementation of a floating and tunable CMOS active inductor. It is based on the classical gyrator-C topology and is enhanced by adding an internal offset reduction mechanism to guarantee functionality also for unbalanced D ...

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 ...

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 ...

A fully integrated Hall sensor microsystem with current-mode output

Maher Kayal, Marc Pastre, Andrea Ajbl

This paper presents a fully integrated Hall sensor microsystem with a current-mode output. The system operates in open-loop and includes a Hall sensor with internal biasing, a fully differential front-end, a preamplifier chain and a voltage-to-current conv ...

Towards circuit design using VeSFETs

Maher Kayal, Jean-Michel Sallese, François Krummenacher, Marc Pastre, Lucian Barbut

This paper explores the potential of VeFETs for mixed-signal circuits. A new physics-based compact DC model of the VeSFET operated in subthreshold region is presented and used to derive 1st-order sensitivities of the device threshold voltage to process var ...

A circuit-level substrate current model for smart-power ICs

Maher Kayal, Jean-Michel Sallese, François Krummenacher, Marc Pastre, Fabrizio Lo Conte

This paper presents a new modeling methodology accounting for generation and propagation of minority carriers that can be used directly in circuit-level simulators in order to estimate coupled parasitic currents. The method is based on a new compact model ...

Global modeling strategy of parasitic coupled currents induced by minority-carrier propagation in semiconductor substrates

Maher Kayal, Jean-Michel Sallese, François Krummenacher, Marc Pastre, Fabrizio Lo Conte

This paper presents a modeling strategy to simulate the propagation of electrical perturbations induced by direct biasing of substrate junctions. Usually, this is done by identifying parasitic substrate devices such as bipolar transistors. However, mapping ...

Methodology for the Digital Calibration of Analog Circuits and Systems Using Sub-binary Radix DACs

Maher Kayal, Marc Pastre

This paper presents a methodology for digitally calibrating analog circuits and systems. Based on the detection of an imperfection by a simple comparator, a successive approximations algorithm tunes a compensation current. The latter is generated by a sub- ...
