Patent number: 9429538Abstract: A MEMS biochemical sensor configured to sense a target molecule, such as a DNA molecule, a protein molecule, and a viruses molecule. The biochemical sensor may include a cell and a readout module. The cell is configured to be coupled to a probe molecule, to retain a pre-sensing charge before the probe molecule is exposed to the target molecule, and to retain a sensing charge after the probe molecule is exposed to the target molecule. The readout module is coupled to the cell and configured to generate a measurement signal based on the pre-sensing charge and the sensing charge.Type: GrantFiled: November 25, 2013Date of Patent: August 30, 2016Assignee: Mikro-Tasarim Elektronik San. ve Tic.

Patent number: 8097904Abstract: The images sensor includes a readout circuit capacitatively coupled to a memory circuit. The readout circuit includes: (i) a photon detector to receive a plurality of photons and to provide a charge signal corresponding to the received photons, (ii) a resettable integrator that is reset multiple times over a single exposure time and provides an analog representation of the incident photons during the last integration cycle, and (iii) a comparator that monitors the integrator output and generates a reset pulse when the integrator reaches a built-in threshold value. The memory circuit includes: (i) a receiver circuit that detects the output of the digital driver in the front-end readout circuit via capacitive coupling and generates a digital voltage pulse for each received signal, and (ii) a digital counting memory to count the received pulses to provide a coarse digital representation of how many times the integrator is reset.Type: GrantFiled: September 7, 2010Date of Patent: January 17, 2012Assignee: Teledyne Scientific & Imaging, LLCInventors: Selim Eminoglu, Stefan C.

Publication number: 20050224714Abstract: Micromachined, CMOS p+-active/n-well diodes are used as infrared sensing elements in uncooled Focal Plane Arrays (FPA). The FPAs are fabricated using a standard CMOS process followed by post-CMOS bulk-micromachining steps without any critical lithography or complicated deposition processes. Micromachining steps include Reactive Ion Etching (RIE) to reach the bulk silicon and anisotropic silicon wet etching together with electrochemical etch-stop technique to obtain thermally isolated p+-active/n-well diodes. The FPAs are monolithically integrated with their readout circuit since they are fabricated in any standard CMOS technology.Type: ApplicationFiled: April 6, 2005Publication date: October 13, 2005Inventors: Tayfun Akin, Selim Eminoglu, M.
