Patent number: 8270316Abstract: An on-chip Radio Frequency (RF) Interconnect (RF-I) for communication between internal circuit nodes of an integrated circuit is provided. In one embodiment, an integrated circuit is provided that includes an on-chip transmission line, a first circuit node associated with an RF transmitter connected to the transmission line, and a second circuit node associated with an RF receiver connected to the transmission line. In order to transmit data from the first circuit node to the second circuit node, the RF transmitter associated with the first circuit node modulates the data onto an RF carrier frequency to provide a modulated RF signal and transmits the modulated RF signal over the transmission line. The RF receiver associated with the second circuit node receives the modulated RF signal from the transmission line and demodulates the modulated RF signal to recover the data for the second circuit node.Type: GrantFiled: January 30, 2009Date of Patent: September 18, 2012Assignee: The Regents of the University of CaliforniaInventors: Mau-Chung F.

Patent number: 7489024Abstract: An array of uncooled infrared sensors based on a micro-machined temperature sensitive MOS transistor. The sensor array is fabricated using a commercial CMOS process on SOI wafers, followed by backside silicon dry etching for each sensor pixel. Active sensor pixels may include either, an integrator and buffer, or simply the sensing transistor, serving also as the selection device. The transistor bias controls the selected device and the sensitivity of the sensor. PMOS transistors and switched operation are used for noise minimization.Type: GrantFiled: February 15, 2004Date of Patent: February 10, 2009Assignee: Technion Research & Development Foundation Ltd.Inventors: Eran Socher, Oflr Bochobza-Degani, Yael Nemirovsky

Patent number: 7412358Abstract: A method of efficiently extracting the pull-in parameters of an electrostatically activated actuator. The actuator is modeled as an elastic element. For each of a plurality of deformations of the elastic element, a corresponding voltage is calculated. The highest such voltage is the pull-in voltage of the actuator. The corresponding deformation is the pull-in deformation of the actuator. Each deformation is defined by fixing a displacement of one degree of freedom of the elastic body and calculating corresponding equilibrium displacements of all the other degrees of freedom without the application of any external mechanical forces to ensure equilibrium. The actuator is altered to optimize whichever pull-in parameter is relevant to the desired application of the actuator.Type: GrantFiled: June 4, 2002Date of Patent: August 12, 2008Assignee: Technion Research and Development Foundation Ltd.Inventors: Ofir Bochobza-Degani, David Elata, Yael Nemirovsky, Eran Socher

Patent number: 7091715Abstract: Method and apparatus for sensing the displacements of micromachined devices and sensors. The method is referred to as the enhanced modulated integrative differential optical sensing (EMIDOS). The target micromachined proof-mass, for which displacements are measured, includes a grid of slits. The micromachined device is bonded to a CMOS chip containing a matching photodiodes array and their readout electronics. The grid is aligned with the photociiodes. An illumination source, such as an LED, is then mounted above the micromachined device. A model for the noise equivalent displacement (NED), including mechanical, electrical and optical domains, as well as all noise sources is derived. The model predicts that displacements below 10?3 [?{square root over ( )}Hz] can be measured. The design comprises innovative inertial sensors, an accelerometer and a rategyroscope employing the EMIDOS. Performance models for the noise equivalent acceleration (NEA) and noise equivalent rate (NER) are also derived.Type: GrantFiled: November 14, 2001Date of Patent: August 15, 2006Assignees: Technion Research & Development Foundation Ltd., Rafael - Armament Development Authority Ltd.Inventors: Yael Nemirovsky, Ofir Degani, Eran Socher, Dan Seter

Patent number: 6350983Abstract: A micro-electromechanical optical inertial sensing device comprises a CMOS chip (3), comprising at least one integrated photodiode (6) and analog electronics; an elastically suspended proof mass (1); and a light source (4). A light beam from the light source casts a partial shadow of the proof mass over the photodiode when the proof mass is at rest. When subjected to an inertial movement, the proof mass swings causing the partial shadow to shift and modulate the illumination of the photodiode. An output current signal from the photodiode is processed by the analog electronics to generate measurement results.Type: GrantFiled: July 21, 2000Date of Patent: February 26, 2002Assignees: Rafael-Armament Development Authority Ltd., Technion Research and Development Foundation Ltd.Inventors: Shmuel Kaldor, Yael Nemirovsky, Ehud Netzer, Dan Seter, Ofir Degani, Eran Socher
