Optimal filtering of an incremental second-order MASH11 sigma-delta modulator

Maher Kayal, Sylvain Maréchal, François Krummenacher

This paper describes an optimal filter design procedure for a cascaded sigma-delta modulator, starting with a block schematic of a second-order topology and deriving step by step the optimal decoder. The presented filter enhances the resolution of the MASH ...

An internally non-linear ADC for a ΣΔ accelerometer loop

Maher Kayal, Marc Pastre

If an analog-to-digital converter (ADC) is used within a ΣΔ converter such that the loop filter is mixed signal, then the ADC does not need to have the full resolution of the ΣΔ converter, and its input values will not be uniformly distributed over the inp ...

High-Speed Power System Stability Simulation Using Analog Computation

Maher Kayal, Laurent Fabre, Ira Nagel

This paper presents a microelectronic emulation approach for high-speed power system computation. First, the problems of existing power system simulators are detailed. This shows that microelectronic emulation is a possible solution for solving the speed p ...

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 ...

SOI digital pixel sensor based on charge pumping

Maher Kayal, Jean-Michel Sallese, Louis Harik

In this paper, a digital pixel sensor in silicon on insulator (SOI) is presented. The active part is a partially depleted SOI phototransistor. The technique elaborated in Harik et al. (2008) [1] was designed and implemented. Moreover, we took advantage of ...

High-speed power system stability simulation using analog computation: Systematic error analysis

Maher Kayal, Laurent Fabre, Ira Nagel

This paper joins a series of papers dealing with high-speed power system emulators. It clarifies the last details about the system level of the AC emulation approach by analyzing and quantifying the systematic errors introduced during modeling. Thereby a n ...

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 ...

Measurement and performance evaluation of a silicon on insulator pixel matrix

Maher Kayal, Jean-Michel Sallese, Louis Harik

A new technique for driving silicon-on-insulator pixel matrixes has been proposed in [1], which was based on transient charge pumping for evacuating the extra photo-generated charges from the body of the transistor. An 8×8 pixel matrix was designed and fab ...
