Electromechanical Modeling beyond VHDL-AMS
IEEE/ACM International Workshop on Behavioral Modeling and Simulation (BMAS), Orlando, Florida, USA
L.M.Voßkämper, A.Lüdecke, M.Leineweber, G.Pelz

Abstract Analytical modeling for electromechanics sometimes requires features like the representation of bended struc- tures, the inclusion of (moving) boundary conditions or spatial integrations and differentiations. All these points are currently not directly addressed in VHDL-AMS and other analog hardware description languages. This paper illustrates this, using the example of a capacitive pressure sensor. The …

A -100 dB THD, 120dB SNR programmable gain amplifier in a 3.3 V, 0.5 µm
ESSCIRC 1997
E.Compagne, G.Martel, P.Senn

Abstract A fully differential amplifier that operates from a 3.3V±10% power-supply and featuring a – 100dB THD at 2Vpp output voltage was realized. Equivalent input noise in the 100Hz – 10kHz audio-band is 4tVrms, leading to a 120dB SNR. This amplifier is used as the core of a programmable gain cell in the front-end part …

Sigma-Delta Converters for Multimedia Applications
Analog & Mixed-signal Design conference, San Jose, California, USA
J.F.Pollet, A.Alegre de La Sougeolle, C.Perrin

Introduction This paper mainly presents macrocells for the design of delta-sigma converters, available in the ASIC library of the SGS-THOMSON BICMOS 1.2 gm technological process. These macrocells can be used to build ASICs containing stereo analog-to-digital and digital-to-analog converters for multimedia audio applications. In a first part, macrocell characteristics and a “kit part” circuit are …
