This paper presents the basis of the modeling of the MOS transistor for circuit simulation at RF. A physical equivalent circuit that can easily be implemented as a Spice subcircuit is first derived. The subcircuit includes a substrate network that accounts ...
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. ...
The inventive method for measuring the optical properties of transparent and/or diffusive objects (18), especially their reflection profile, uses two coupled interferometers. Said coupled interferometers are operated with two beams of different coherence l ...
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 ...
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 ...
The bandwidth of holographic recording in LiNbO3 (Fe doped) in the 90 degrees geometry is studied theoretically and experimentally. The wide holographic bandwidth of LiNbO3 makes it possible to record submicrometer pixels and reconstruct them by phase conj ...
A low-power and low-voltage (LP/LV) RF front-end operating at 430MHz and implemented in a standard 0.5 mu m digital CMOS process is described. Specific LP/LV bias techniques and design tradeoffs are discussed and their application to the design of a fully ...
The paper presents an original analog-to-digital converter (ADC) array meeting the constraining requirements in resolution, speed, size, and low power consumption of high-performance low-cost video cameras. The converter array is based on ADC cells relying ...
An automatic offset compensation scheme for 2 stages operational amplifier is described. The presented technique can be applied to an existing OA core cell without modifying its design. Offset voltage is reduced by digitally adjusting the resulting offset ...
The Quench of Long Length (QUELL) experiments have been completed. The US contribution was to develop and implement both conventional and novel techniques in quench detection. The results of the quench detection experiments demonstrate that all US systems ...
