Patent number: 9660679Abstract: A wireless receiver automatic gain control system includes: a coarse amplification subsystem that receives and amplifies a carrier-modulated signal; a demodulator that generates a baseband signal from the amplified carrier-modulated signal; a fine amplification subsystem that amplifies the baseband signal; and a controller connected to the amplification subsystems. The controller: obtains a unified gain value for the amplification subsystems; based on the unified gain value, selects (i) one of a plurality of coarse gain values defining a set of coarse gain steps each spanning a plurality of unified gain steps, and (ii) one of a plurality of fine gain values defining a set of fine gain steps each spanning a single unified gain step; and sets (i) the gain of the coarse amplification subsystem to the selected coarse gain value, and (ii) the gain of the fine amplification subsystem to the selected fine gain value.Type: GrantFiled: July 26, 2016Date of Patent: May 23, 2017Assignee: PERASO TECHNOLOGIES INC.Inventors: Grigori Temkine, Craig Farnsworth, Arash Tabibiazar, Alexander Tomkins, Bradley Robert Lynch

Patent number: 8861627Abstract: In one embodiment, a circuit comprises a first pair of elements, a second pair of elements, a combiner, and a signal output. Each element in the first and second pair of elements comprises an amplitude-control input for receiving an amplitude-control bit, a phase-control input for receiving a phase-control bit, a signal input for receiving an input signal, a modulator for producing an output signal based on the amplitude-control bit, the phase-control bit, and the input signal, and an signal output for transmitting the output signal to the combiner. The combiner combines the two output signals from the first and second pair of elements to produce an output signal for the circuit to be transmitted by the signal output of the circuit.Type: GrantFiled: July 15, 2009Date of Patent: October 14, 2014Assignee: Fujitsu LimitedInventors: Sorin P. Voinigescu, Alexander Tomkins, Magnus O. Wiklund, William Warren Walker

Patent number: 8676136Abstract: A radio antenna switch module for a high frequency radio transceiver enables the radio transceiver to have a small number of receivers and transmitters and a larger number of antennas, whereby each antenna has a different diversity characteristic. The diversity between antennas provide for greater communication reliability, while the small number of receivers and transmitters allows the transceiver to operate at relatively low power compared to conventional radio transceivers. The switch module also allows for two loopback modes between the transmitter and the receiver for at-speed, low-cost self-test in production.Type: GrantFiled: January 25, 2012Date of Patent: March 18, 2014Assignee: Peraso Technologies, Inc.Inventors: Sorin Voinigescu, Alexander Tomkins, Andreea Balteanu, Ioannis Sarkas, Katya Laskin
