Analog & Mixed Signal IC Debug: A high precision ADC application
F.Poullet

Introduction Increasing pressure on production costs and, more generally, time to market, have impacted all levels of IC design. In this context, one of the major challenges is to avoid silicon failure or yield loss. Indeed, a widely accepted statistic today is that almost half of all designs fail at first silicon. Failure costs are …

A novel technique to create behavioral models of differential oscillators in VHDL-AMS
Xth Inter. Workshop on Symbolic & Numerical Methods, Modeling & Applications to Circuit Design, Erfurt, pp.241-246
M.Kraemer, D.Dragomirescu, R.Plana

Abstract This paper describes an approach to model the transient and steady state behavior of differential microwave oscillators at the system level. Furthermore, phase noise characteristics can be emulated by the resulting models. The mathematical structure consist of a set of algebraic and differential equations that are solved by a VHDL-AMS interpreter. The nonlinearity occurring …

VHDL-AMS models of millimeter-wave oscillators for simulations of system-on-chip behavior
Colloque GDR SOC SIP, Paris (France), 2p. M. Kraemer, D. Dragomirescu, R. Plana

Introduction For future high-data rate communication systems the ultra-large frequency band around 60 GHz represents a promising alternative to the overcrowded spectra available at lower frequencies. To avoid connection losses and achieve small system size and very low cost, the transceivers will typically be designed as System on Chip (SoC) in a low cost silicon …

Keeping the best audio quality in mobile phone by managing voltage drops created by 217 Hz transients
M.Maurel

Source of major noise Whatever the protocol used by a mobile phone, GSM or TDMA, RF transmitter switching creates the most notorious noise for the power supply. The RF power amplifier switches on and off at a rate of 217 Hz. At each of these events, a high current (up to 1.7A) is drawn from …

Yield prediction in an automotive MEMS application with help of statistical analysis packages SAE J2748
4. ASIM Workshop, Wismar, ISBN 9783901608339, P. 251-256
D.Dammers, D.Schollän, L.M.Voßkämper

Abstract This paper shows a methodology for the yield prediction of Micro Electro Mechanical Systems (MEMS). Variations of process properties during the production of MEMS are considered in system simulations. Yield prediction based on the distribution functions provided by statistical analysis packages SAE J2748 is demonstrated on a capacity based accelerometer system… Download this press …
