In this paper a gradual investigation of a particular Hall sensor in SOI (“Silicon-On-Insulator”) technology is presented. The most important parameters of a specific Hall cell, based on SOI structure, are evaluated through three-dimensional physical simulations. The fact that the depth of the active silicon layer in SOI integration process is much smaller than in a regular CMOS is immediately reflected...
Application of hardware description languages (e.g. Verilog, VHDL) to create design model and logic synthesis tools to generate its physical implementation is preferred design paradigm. In this paper it is examined how the modeling style used to implement the thermometer-to-binary encoder influence parameters of the synthesized circuit. It is demonstrated that badly chosen language statements and...
Noise canceling techniques have been successfully applied to the design of modern multi-band RF-CMOS inductor-less receivers. However, low voltage supply requirements are imposing new design challenges which are pushing the operation of the MOS transistor into moderate or weak inversion, making the setup of closed sizing expressions a difficult task. This paper presents a Si2 OpenAccess based circuit...
High voltage CMOS active devices inherently have a parasitic vertical bipolar transistor. The parasitic PNP structure can be activated during high-power switching operation causing a potential shift of the substrate. In this work a spice-modeling approach based on transistor layout is presented that is compatible with parasitic substrate noise propagation in Smart Power ICs. The results of the model...
Lab-on-chips (LOCs) are small systems, which integrate, in the same device, several functions involving chemical analysis with bio-processing functionalities typically performed in a laboratory. As a consequence, it is a multi-domain system that can be described and designed with VHDL-AMS, a hardware description language that natively supports electronics, thermics and fluidics. On the other hand,...
Research and development in life sciences domain brings every day many innovations. Some of them have been enabled (or improved) by the micro-electronics. Several examples are described in this paper. A big challenge in the design of such systems is that the biological part cannot be uncoupled from the rest of the system during the design process. The integration of biological parts in system's design...
