A low power, low chip area decimation filter for Σ - Δ modulator for flywheel MEMS gyro realized in the CMOS 180 nm technology

Pierre-André Farine, Rafal Tomasz Dlugosz, Steve Tanner, Patrick Stadelmann

The paper presents a low power and low chip area decimation filter for a 15-bits Σ-Δ analog-to-digital converter (ADC) designed for a flywheel MEMS gyroscope. In contrary to typical solutions, in which decimation is performed after each filtering stage, in ...

A speckle-based CMOS sensor for arbitrary surface movement detection with correlated double sampling and gain error correction

Pierre-André Farine, Chao Wang, Steve Tanner

We present a CMOS sensor for accurate tracking of speckle movements on arbitrary surfaces. The sensor is made of a pair of comb filters with a pitch of 5.6 mu m and decayed by 90 degrees to produce quadrature signals. The readout circuit is a 60 dB amplifi ...

Comparing defect characterization techniques with non-radiative multiphonon charge trapping model AC analysis, trap-assisted-tunneling and charge pumping

Alexandre Schmid, Davide Garetto

The advantages and drawbacks of Capacitance vs Voltage (CV) characteristics, trap-assisted gate leakage tunneling and multi-frequency charge pumping techniques, have been brought out through an attentive investigation of oxide defects in CMOS technologies. ...

Electrophysiological imaging of epileptic brain slices reveals pharmacologically confined functional changes

Diego Ghezzi

Microelectrode arrays (MEAs) are employed to study extracellular electrical activity in neuronal tissues. Neverthe- less, commercially available MEAs provide a limited number of recording sites and do not allow a precise identifi- cation of the spatio-temp ...

Polysilicon Nanowire Transistors and Arrays Fabricated With the Multispacer Technique

Giovanni De Micheli, Yusuf Leblebici, Mohamed Haykel Ben Jamaa

In this paper, we demonstrate the ability of the multi- spacer patterning technique to yield layers of polycrystalline silicon nanowires with a sublithographic pitch, by exclusively using micrometer resolution and CMOS processing steps. We characterize sin ...
