This paper presents the design and the practical realization of a measurement system dedicated to fast real-time multichannel registration of electronic system thermal response. The response is registered in parallel channels with a frequency up to 1 MHz. Such a high frequency is required for the thermal identification of electronic systems. The designed circuit is used here for the investigation...
The ultimate research goal for unmanned aerial vehicles (UAVs) is to facilitate autonomy of operation. Research in the last decade has highlighted the potential of vision sensing in this regard. Although vital for accomplishment of missions assigned to any type of unmanned aerial vehicles, vision sensing is more critical for small aerial vehicles due to lack of high precision inertial sensors. In...
In this paper, we present a non-volatile register based on hybrid Spintronics/CMOS technology, which can store securely and non-vocatively all the intermediate data in the logic circuits as FPGA and ASIC. The non-volatility of this register allows to power down the circuits keeping the data thereby reduce significantly the standby power and accelerate the chip re (boot) latency. Based on STMicroelectronics...
Micromachined inertial sensors offer new applications and opportunities for improved mobile devices. Especially the consumer market for micromechanical motion sensing through gyroscopes is widely emerging. The integration of inertial sensors within portable devices enforces suitable power management concepts to handle and achieve the tight power budget of the electronic devices. This paper presents...
The magnetometer front-end ASIC (MFA) is a device for reading out magnetic field sensors which are based on the fluxgate principle. The instrument was developed at the Space Research Institute (IWF) of the Austrian Academy of Sciences and is part of the magnetospheric multi scale (MMS) mission organized by NASA. In the MMS configuration the ASIC is positioned inside the spacecraft while the sensor...
SpaceWire is a network for connecting instruments and other equipment into the payload data-handling system onboard a spacecraft. It provides high-speed (2-200 Mbits/s), bi-directional communications over point-to-point links and network capabilities using routing switches. One of the key features of SpaceWire is its simplicity resulting in low gate count implementations enabling SpaceWire interfaces...
This paper deals with the implementation of a CMOS analog neural network (NN) that has to be integrated in a new kind of optoelectronic measurement system. The aim is to achieve real-time surface recognition using a phase-shift rangefinder and a neural network. NN architecture is a multilayer perceptron (MLP) with two analog input signals provided by the rangefinder, three processing neurons in the...
