Pressure sensor data processing for vertical velocity measurement

Husak M., Jakovenko J., Stanislav L., Czech Technical University in Prague, CZ

There are design and realization of a sensor system for vertical velocity measurement using pressure sensor in the paper. Problem of nonlinearity due to the exponential function of air pressure versus altitude is discussed in [...]

LINFET: A BSIM class FET model with smooth derivatives at Vds=0

Wagner L., Olsen C.M., IBM Systems Technology Group, US

The linearity of compact transistor models near Vds=0 is important for designing RF circuits. Currently compact models such as BSIM3/4 have problems around this bias point due to discontinuities in the derivatives. Recently, the PSP [...]

A Computationally Efficient Method for Evaluating Distortion in DG MOSFETs

Salazar R., Ortiz-Conde A., García-Sánchez F.J., Solid State Electronics Laboratory, VE

In this paper we have generalized the correlation between Integral Nonlinearity Function (INLF) and Total Harmonic Distortion (THD) of independently driven double -gate (IDDG) MOSFETs.

Two-Tone Distortion Modeling for SiGe HBTs Using the High-Current Model

Malladi R.R., Borich V., Sweeney S.L., Rascoe J., Newton K.M., Venkatadri S., Yang J., Chen S., IBM Systems and Technology, US

This paper examines certain aspects of the base resistance model of HiCUM (High Current Model) to address convergence problems seen during 2-tone distortion simulations of SiGe HBTs. Here, we propose some changes to the model [...]

RF Applications of MOS Model 11

van Langevelde R., Scholten A.J., Tiemeijer L.F., Havens R.J., Klaassen D.B.M., Philips Research Laboratories, NL

RF-CMOS applications impose increasingly stringent requirements on compact models used in circuit simulation. In this paper several of these issues will be addressed together with a discussion of the state-of-the-art of compact modelling.
