Today's world of electronics becomes more and more digital and therefore CMOS becomes the dominant technology. A CMOS process compared to a bipolar process offers several advantages, mainly a low power consumption which is important for portable systems po ...
We have fabricated two-dimensional inductive devices by integrating micropatterned magnetic foils of high permeability (µr=100000) with winding patterns realised in printed circuit boards (PCBs) and flex-foil technology. We realise relatively high inductan ...
Batch and continuous-flow measurements of codeine were performed by electrochemiluminescence, using a miniaturized sensor combining transduction electrodes and a photodetector on the same silicon chip. In the case of flow measurements, a flow channel was a ...
A new fully integrated two-stage operational transconductance amplifier-capacitor (OTA-C) sine oscillator circuit configuration using a 0.5 μm CMOS digital process is described. A simple linear impedance analysis is presented to predict the amplitude and d ...
A low-power 14-bits first order incremental Analog-to-Digital Converter (ADC) is presented. Based on the charge balancing principle, this switched-capacitor (SC) circuit integrates the input signal multiple times to reach the targeted resolution, linearity ...
In this study, synchronization state of the coupled chaotic circuit is investigated when a sinusoidal input signal is added by both of computer simulations and circuit experiments. It is confirmed that the synchronization state changes by the values of the ...
Tuning and high frequency capabilities and dynamic range performance of continuous-time oscillators and filters, using the weak inversion operation mode of a low-cost conventional 0.5 μm CMOS technology and multi-tanh linearisation technique are examined. ...
Abstract—A common problem when using piezoceramic actuators for precise positioning is their hysteresis. Either external sensors such as capacitive or inductive probes, optical sensors or strain gauges are commonly used. The latter are the most favorable s ...
This paper reports on the design, fabrication, and characterization of the first low-power consumption MOSFET gas sensor. The novel MOSFET array gas sensor has been fabricated using anisotropic bulk silicon micromachining. A heating resistor, a diode used ...
With advances in micromachining and the consequent growing sophistication of microstructures, emphasis is increasingly being laid on the design and realization of complete microsystems. In this paper we will show some possible combinations of micromaching ...
