CAD tools for fast analysis of parasitic coupling and mismatch effects in switched-capacitor circuits

Maher Kayal, Sylvain Maréchal, François Krummenacher

This paper presents a switched-capacitor simulator, optimized for fast computations. Two CAD tools are implemented in order to perform Monte-Carlo simulations, to identify sensitive parasitic coupling prior to layout and to rapidly verify parasitic couplin ...

Optimal filtering of incremental first-order sigma-delta modulators with sweep input

Maher Kayal, Sylvain Maréchal, François Krummenacher

In this paper, an optimal filter design procedure is described, from the equation representing the behaviour of a ΣΔ modulator to a functional algorithm. The first section shows the design of an optimal filter for a first-order ΣΔ ADC with a constant input ...

Meshing strategy of equivalent substrate schematic in SMART power IC

Maher Kayal, Jean-Michel Sallese, Fabrizio Lo Conte

In this paper, a modeling methodology able to create an equivalent schematic of an High-Voltage integrated circuit is developed. The equivalent schematic is based on enhanced model of diodes and resistances, accounting for minority and majority carrier pro ...

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 ...

Hall effect sensors performance investigation using three-dimensional simulations

Maher Kayal, Jean-Michel Sallese, Maria-Alexandra Paun

Several Hall effect sensors were modeled and evaluated regarding the Hall voltage and sensitivity using 3D physical simulations. For accurate results the numerical offset and its temperature drift were analyzed. The versatility of the simulation allows var ...

Circuit Level Modeling Methodology of Parasitic Substrate Current Injection from a High-Voltage H-bridge at High Temperature

Maher Kayal, Jean-Michel Sallese, Fabrizio Lo Conte

In this paper, a modeling methodology is validated based on an enhanced model of the diode, that we have developed to simulate substrate current coupling mechanisms on a typical H -bridge structure. An equivalent schematic based on an enhanced model of the ...
