Journal ArticleDOI

The extended gate chemically sensitive field effect transistor as multi-species microprobe☆

TL;DR: In this article, a multi-species microprobe structure for potentiometric measurements and the appropriate patterning techniques of the chemically-sensitive membranes is described, which allows successive patterning of both vacuum-deposited inorganics and spin coated polymers and gels.
Journal ArticleDOI

1.05-GHz CMOS oscillator based on lateral- field-excited piezoelectric AlN contour- mode MEMS resonators

TL;DR: The first demonstration of a 1.05-GHz microelectromechanical oscillator based on lateral-field-excited (LFE) piezoelectric AlN contourmode resonators, which satisfies the global system for mobile communications (GSM) requirements for ultra-high frequency (UHF) local oscillators (LO).
Book ChapterDOI

A Foveated Retina-Like Sensor Using CCD Technology

TL;DR: A CCD imager whose sampling structure is loosely modeled after the biological visual system is described, which has embedded in its structure a logarithmic transformation that makes it size and rotation invariant.
Journal ArticleDOI

Nonparallel training for voice conversion based on a parameter adaptation approach

TL;DR: The proposed algorithm is based on speaker adaptation techniques, adapting the conversion parameters derived for a particular pair of speakers to a different pair, for which only a nonparallel corpus is available.
Journal ArticleDOI

Reconfigurable CMOS Oscillator Based on Multifrequency AlN Contour-Mode MEMS Resonators

TL;DR: In this article, a reconfigurable complementary metal-oxide-semiconductor (CMOS) oscillator based on microelectromechanical system (MEMS) resonators operating at four different frequencies (268, 483, 690, and 785 MHz) is presented.
