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 …

A current mirror model in Verilog-AMS
Published in the proceedings of the 22th South Symposium on Microelectronics and 1st Symposium AUGM on Microelectronics, Porto Alegre, Brazil.
M.Neumann, P.da Silva, O.Gouveia Filho

Abstract This work presents a model of a simple current mirror implemented in Verilog-AMS language using the circuit simulator Smash. The model is validated through comparisons with simulations made with the ACM model implemented in Smash. Simulations with the current mirror used to bias a Differential CMOS Amplifier is shown in order to illustrate the …
