The use of full color-sensitive photodetectors with three electrically tunable spectral responses allows the design of sensors that can be real-time reconfigured for different color acquisition modes. All the (physically identical) pixels can be biased in the same way, each giving the same set of RGB spectral responses: in this situation the conversion from(More)
The Transverse Field Detector (TFD) is a filter-less and demosaicking-less color sensitive device that easily allows the design of more than three color acquisition channels at each pixel site. The separation of light into different wavelength bands is based on the generation of transverse electric fields inside the device depleted region, and exploits the(More)
—A new micromachined uniaxial silicon resonant ac-celerometer characterized by a high sensitivity and very small dimensions is presented. The device's working principle is based on the frequency variations of two resonating beams coupled to a proof mass. Under an external acceleration, the movement of the proof mass causes an axial load on the beams,(More)
The development of color pixels in modern digital imaging has led to devices in which color detection is not based on the use of physical color filters but relies on the wavelength dependence of the silicon absorption coefficient in the visible range. In some of these devices the responsivity of each color channel can be electrically tuned by changing the(More)
—The combination of multiaxis and multiparameter microelectromechanical systems (MEMS) in the same technology would result in very cheap and smart inertial measurement units (IMUs). In this paper, a Z-axis Lorentz-force-based magnetometer whose design and optimization are reviewed taking into account the constraints of an industrial MEMS technology (process(More)
