Design Methodology for Controlled-Q Resonators in OTA-based Filters

Pierre-André Farine, Cyril Botteron, Saeed Ghamari, Gabriele Tasselli

This paper presents a design methodology for high quality factor resonators based on operational transconductance amplifier (OTA) employed in active filters. The quality factor of a resonator, as its main specification, is translated to the requirements of ...

Sensitivity and open-loop control of stochastic response in a noise amplifier flow: the backward-facing step

François Gallaire, Edouard Boujo

The two-dimensional backward-facing step flow is a canonical example of noise amplifier flow: global linear stability analysis predicts that it is stable, but perturbations can undergo large amplification in space and time as a result of non-normal effects ...

Implementation and Characterization of Dynamic Genetic Networks in Vitro

Henrike Marie Niederholtmeyer

Transcription and translation (TX-TL) can be performed in vitro, outside of cells, allowing the assembly and analysis of genetic networks. This approach to engineering biological networks in a less complex and more controllable environment could one day al ...

Simple thermal noise estimation of OTA-based switched-capacitor filters

Christian Enz, François Krummenacher, Assim Boukhayma

This paper presents a new analytical method to simply estimate the integrated thermal noise in switched-capacitor filters (SCF). It is shown how the Bode theorem, which is theoretically valid only for continuous-time passive filters, can be extended to als ...

A Versatile 1.4-mW 6-bits CMOS ADC for Pulse-Based UWB Communication Systems

Frédéric Chastellain, Pierre-André Farine, Cyril Botteron, Christian Robert, Saeed Ghamari

An Analog to Digital Converter (ADC) using the low duty-cycle nature of pulse-based Ultra Wide-Band (UWB) communications to reduce its power consumption is proposed. Implemented in CMOS 180 nm technology, it can capture a 5 ns window at 4 GS/s each 100 ns, ...

Digitization Technique for UWB Receiver and Capacitive Sensor Interface

Shenjie Wang

As CMOS processes continue to scale to smaller dimensions, the increased fT of the devices and smaller parasitic capacitance allow formore power efficient and faster digital circuits to be made. But at the same time, output impedance of transistors has gon ...
