Patent number: 9341661Abstract: A tone detector is disclosed that is realizable in digital embodiment on a single integrated circuit die and does not require external components, such as a discrete capacitor. An input connects to a comparator, which in turn connects to one or more edge detectors and a flip flop. The edge detector outputs a pulse responsive to a detected edge. A counter is reset by the pulses from the edge detectors thereby preventing the counter from reaching a maximum value, which would otherwise be output from the counter and provided to a flip flop to clock in the comparator output at the D input to the flip flop. In operation, the comparator generates a rail to rail signal responsive to a received tone, which in turn is clocked through the flip flop as a logic high output indicating presence of a tone.Type: GrantFiled: February 15, 2013Date of Patent: May 17, 2016Assignee: Skyworks Solutions, Inc.Inventor: Amit Burstein

Patent number: 6392470Abstract: The invention relates to a device for transitioning a bandgap reference circuit to its operational mode, of supplying a reference voltage, when power is supplied to the combined circuits. The device is comprised of a supply-independent biasing circuit that is electrically connected to a start-up circuit and supports the start-up circuit's ability to cause a bandgap reference circuit to transition to its operational mode for any supply voltage that supports the bandgap reference circuit's operational mode.Type: GrantFiled: September 29, 2000Date of Patent: May 21, 2002Assignee: International Business Machines CorporationInventors: Amit Burstein, Daniel Shkap

Patent number: 6271652Abstract: The invention relates to a voltage regulator providing high immunity to DC variations of a power supply. The voltage regulator comprises a voltage regulator circuit, a gain stage that is connected to the output of the voltage regulator circuit, and a voltage modulation device forming a signal feedback loop between an output and an input of the gain stage. An initial reference voltage is generated by the voltage regulator circuit and provided to an input of the gain stage. The difference between this initial reference voltage and a fractional portion of the feedback signal, from the voltage modulation device, is amplified by the gain stage. The amplified signal of the gain stage is used to modulate the reference voltage provided to an external load. Better DC accuracy and stability is obtained by using a two stage amplifier to increase the loop gain of the voltage regulator.Type: GrantFiled: September 29, 2000Date of Patent: August 7, 2001Assignee: International Business Machines CorporationInventors: Amit Burstein, Daniel Shkap

Patent number: 5994985Abstract: A high-performance integrable tunable inductor includes a "primary" coil and a "drive" coil placed in close proximity to each other and simultaneously driven with primary and drive currents, respectively. The drive current induces mutual components of inductance in the primary coil which vary with the phase and amplitude relationship between the two currents. These relationships are controlled to precisely establish the impedance of the primary coil, allowing the inductor to be "tuned" to provide a desired inductance or resistance by simply varying the phase and amplitude relationships appropriately. Inductance values tunable over ranges of about 2:1 and Q values of nearly 2000 have been demonstrated. The primary coil can also be made to operate as a relatively large integrated capacitance by setting the phase and amplitude relationships appropriately.Type: GrantFiled: December 5, 1997Date of Patent: November 30, 1999Assignee: Rockwell Science Center, LLCInventors: David R. Pehlke, Amit Burstein, Mau Chung F. Chang

Patent number: 5659195Abstract: Improved microsensors are provided by combining surface micromachined substrates, including integrated CMOS circuitry, together with bulk micromachined wafer bonded substrates which include at least part of a microelectromechanical sensing element. In the case of an accelerometer, the proof mass is included within the wafer bonded bulk machined substrate, which is bonded to the CMOS surface machine substrate, which has corresponding etch pits defined therein over which the wafer bonded substrate is disposed, and in the case of accelerometer, the proof mass or thin film membranes in the case of other types of detectors such as acoustical detectors or infrared detectors. A differential sensor electrode is suspended over the etch pits so that the parasitic capacitance of the substrate is removed from the capacitance sensor, or in the case of a infrared sensor, to provide a low thermal conductance cavity under the pyroelectric refractory thin film.Type: GrantFiled: June 8, 1995Date of Patent: August 19, 1997Assignee: The Regents of the University of CaliforniaInventors: William J.
