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 …

Introduction Integration of Systems On Silicon needs: interfaces with the analog external world in the same advanced processes than complex digital functions with the same constraints of time to market The answer is: Mixed Signal Virtual Components What kind of functions may be offered, what are the constraints Download this press release

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 …

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 …
