Patent number: 8614572Abstract: An integrated magnetic field generation and detection platform is described that is capable of manipulating and detecting individual magnetic particles, such as spherical super-paramagnetic beads, and providing biosensing functionality. The platform is implemented in an integrated circuit, a portion of the surface of which is functionalized with one or more biochemical agents that binds tightly (i.e., specifically) with a target analyte. The magnetic beads are similarly functionalized with one or more biochemical agents that that bind specifically with the target analyte. When a sample is introduced, magnetic beads that specifically bind to the integrated circuit can be separated from non-specifically bound beads and detected.Type: GrantFiled: July 15, 2010Date of Patent: December 24, 2013Assignee: The Regents of the University of CaliforniaInventors: Octavian Florescu, Bernhard E.

Patent number: 7551021Abstract: A low-leakage circuit includes first, second, and third transistors, which may be P-channel or N-channel FETs. The first transistor provides an output current when enabled and presents low leakage current when disabled. The second transistor enables or disables the first transistor. The third transistor connects or isolates the first transistor to/from a predetermined voltage (e.g., VDD or VSS). The circuit may further include a pass transistor that provides a reference voltage to the source of the first transistor when the first transistor is disabled. In an ON state, the first transistor provides the output current, and the second and third transistors do not impact performance. In an OFF state, the second and third transistors are used to provide appropriate voltages to the first transistor to place it in a low-leakage state. The first, second, and third transistors may be used for a low-leakage current source within a current mirror, an amplifier stage, and so on.Type: GrantFiled: June 22, 2005Date of Patent: June 23, 2009Assignee: QUALCOMM IncorporatedInventor: Octavian Florescu

Patent number: 7323944Abstract: A PLL includes a charge pump, a loop filter, a VCO, and a calibration unit. The calibration unit performs coarse tuning to select one or multiple frequency ranges, performs fine tuning to determine an initial control voltage that puts the VCO near a desired operating frequency, measures the VCO gain at different control voltages, and derives VCO gain compensation values for the different control voltages. The calibration unit also pre-charges the loop filter to the initial control voltage to shorten acquisition time, enables the loop filter to drive the VCO to lock to the desired operating frequency, and performs VCO gain compensation during normal operation. For VCO gain compensation, the calibration unit measures the control voltage, obtains the VCO gain compensation value for the measured control voltage, and adjusts the gain of at least one circuit block (e.g., the charge pump) to account for variation in the VCO gain.Type: GrantFiled: April 11, 2005Date of Patent: January 29, 2008Assignee: Qualcomm IncorporatedInventors: Octavian Florescu, Amr M.

Publication number: 20070112793Abstract: Provided are a method, system, and program for a model publishing framework. An intermediate data structure is generated from a model to include elements providing information on the model, wherein the model defines an object oriented program design. A publisher registry has a plurality of registered publishers. One registered publisher is selected from the publisher registry to use to publish the model. The publisher includes formatting information to generate model output. The selected publisher accesses the intermediate data structure and generates output from the elements in the intermediate data structure according to the formatting information to provide a visualization of the defined model.Type: ApplicationFiled: November 14, 2005Publication date: May 17, 2007Inventors: Octavian Florescu, Ian Leslie, Cheng-Yee Lin

Patent number: 7002390Abstract: Techniques for compensating for propagation delay differences between signals distributed within a logic circuit. A delay matching circuit mimics the internal clock-to-Q delay produced by a flop. The delay matching circuit is placed in the propagation path of an original signal, such as a clock signal, to be redistributed. In general, the delay matching circuit may include a propagation gate multiplexer have a particular configuration. The delay matching circuit imposes a delay substantially equal to the clock-to-Q delay experienced by divided versions of the original signal. In this manner, the delay matching circuit ensures that the rising and falling edges of the original signal and the divided signal are in substantial alignment, enabling synchronous operation. Hence, the delay matching circuit is capable of synchronizing the redistributed and divided signals.Type: GrantFiled: February 7, 2005Date of Patent: February 21, 2006Assignee: Qualcomm IncorporatedInventor: Octavian Florescu
