Abstract. This paper presents an approach for modeling and simulation of a new 2D acceleration sensor array using SystemC-AMS. The sensor array consists of six single acceleration sensors with different detection axes. These single sensors comprise of four capacitive segments and one mass segment, aligned in a semicircle. The redundant sensor information is used for offset correction.Modeling of the single sensors is achieved using sensor structure simplification into 11 points and analytic equations for capacity changes, currents and torques. This model was expanded by a PWM feedback circuit to keep the sensor displacement in a linear region. In this paper the single sensor model is duplicated considering different positions of the seismic mass resulting in different detection axes for the single sensors. The measured accelerations of the sensors are merged with different weights depending on the orientation. This also reduces calculation effort.

This paper describes the ENERSAVE research project, which is funded by the German ministry of research. The project target is a 30 percent power reduction for network nodes via introduction of a holistic, energy‐aware design flow for application‐specific integrated circuit (ASIC) and field programmable gate array (FPGA) design. Using today's state of the art design methods, advanced calculation of system power budgets is a major challenge since current methods do not offer sufficient means for supporting energy awareness and efficiency throughout the complete component design process. The ENERSAVE project is developing a methodology to support power awareness and provides the ability to target power constraints from the system level all the way down to the silicon. It introduces formal tools for power optimizations and demonstrates, on an optical transmission system card, how using this new design methodology enables the envisioned power target to be achieved. The paper presents methodology improvement results to date and offers a preview of expected demonstrable results by project completion in 2014. © 2013 Alcatel‐Lucent.

The development of a new sensor generation with a significant performance gain is mainly aimed at increasing the sensitivity. In addition to that, a variety of properties such as integrability, power consumption, robustness, reliability, cross-talk sensitivity, and others, can be equally important. Some properties scale directly with sensitivity, whereas others show trade-off characteristics. An overview of different approaches for new sensor generations with enhanced performance is presented and discussed in this article. The main focus is on new microelectromechanical systems (MEMS) elements, fabricated within a standard high-aspect-ratio micromachining process and capacitive working principle. Herein, a novel MEMS-based bandpass, a gap reduction technique, fluted electrodes for reduced damping, and a novel direct current/direct current (DC/DC) converter, is proposed. Acoustic emission sensing is chosen as example application to underline the challenging requirements for the design. Furthermore, the recent improvements in technology are presented. Based on bonding and deep reactive ion etching (BDRIE), it allows larger aspect ratios as well as through-silicon vias and low-pressure encapsulation. Consistent further miniaturization leads to the use of nanoscopic elements within MEMS as sensing component instead of the conventional electrostatic working principle. Unique properties of graphene rolls or carbon nanotubes (CNTs) enable promising sensitivity improvements if they are integrated at wafer-level. Therefore, a design concept and formal verification-tool is presented.
