Publication number: 20180034488Abstract: A method, system and circuit for providing for part or all of a transmitter, when it is in mute mode (not actively transmitting), to be turned off, removed, decoupled or modified in general in order to reduce the total noise submitted by the transmitter to the wired network into network controller. In parallel, an auxiliary circuit or impedance is added or coupled to the transmitter in order to mitigate the total return loss change of the transmitter. When in active transmitter mode, this auxiliary circuit or impedance will be removed or decoupled from the transmitter and transmitter will transmit in normal mode.Type: ApplicationFiled: October 12, 2017Publication date: February 1, 2018Inventors: Payman Hosseinzadeh-Shanjani, Branislav Petrovic

Patent number: 9590666Abstract: Methods and systems are provided for mitigating noise and/or impedance effects in transmitters. The mitigation comprises, when transmitter is in a non-active mode, decoupling at least a portion of the transmitter and coupling an auxiliary component to a remaining portion of the transmitter. When the transmitter is in an active mode, the auxiliary component is decoupled from the remaining portion of the transmitter, and the at least a portion of the transmitter is coupled to the remaining portion of the transmitter. The auxiliary component comprises one or more of: a resistive element, a capacitive element, and a reactive component. The auxiliary component is configured such that it may achieve a small mismatching error.Type: GrantFiled: July 28, 2015Date of Patent: March 7, 2017Assignee: ENTROPIC COMMUNICATIONS, LLCInventors: Payman Hosseinzadeh-Shanjani, Branislav Petrovic

Publication number: 20080279262Abstract: An integrated circuit radio transceiver and method therefor includes transmit-receive selection circuitry that in a transmit mode, enables a circuit path between an output stage amplifier and an output node or antenna and disables a circuit path between an input amplifier and the output node or antenna. Alternatively, in a receive mode, the circuitry disables the transmit circuit path and enables the second circuit path. The transmit circuit path including transmit front end circuitry, the receive circuit path including receive front end circuitry and all circuitry for enabling and disabling are all on the same integrated circuit as the first and second circuit paths. The specific topologies avoid exceeding breakdown voltages of on-chip transistors used for transmit-receive circuitry operation.Type: ApplicationFiled: May 7, 2007Publication date: November 13, 2008Applicant: BROADCOM CORPORATIONInventor: Payman Hosseinzadeh Shanjani

Patent number: 7102444Abstract: A method and apparatus for an amplifier, such as a radio frequency amplifier embodiment as an integrated circuit is disclosed. Embodiments provide for operating with good energy efficiency at multiple power levels. Resonant components act to provide consistent operating parameters over the wide range of power levels used. A compensating impedance is switched into or out of circuit in high power mode to improve the match that would pertain without the compensation. Improved compensation and linearity may be provided using features disclosed. The invention may operate in the microwave region or at other RFs.Type: GrantFiled: September 24, 2004Date of Patent: September 5, 2006Assignee: ANADIGICS, Inc.Inventors: Payman Hosseinzadeh Shanjani, Hamid Reza Rategh
