Patent number: 10637397Abstract: Method and apparatus for determining a clock frequency for an electronic processor are provided. One embodiment provides a clock generator for determining a clock frequency for an electronic processor and providing a clock signal to the electronic processor. The clock generator includes a crystal oscillator producing a reference signal and a phase locked loop receiving the reference signal and configured to generate the clock signal based on the reference signal. The clock generator also includes a tuning logic controller electrically coupled to the phase locked loop. The tuning logic controller is configured to program the phase locked loop to a first frequency and determine an integrated circuit process corner of the electronic processor. The tuning logic controller is also configured to determine a second frequency based on the integrated circuit process corner and program the phase locked loop to the second frequency.Type: GrantFiled: August 8, 2017Date of Patent: April 28, 2020Assignee: MOTOROLA SOLUTIONS, INC.Inventors: Mark Rozental, Claudine Tordjman, Richard S. Young, Uri Vallach

Patent number: 8995512Abstract: Receivers (500) and methods of adaptively adjusting the receivers based on a received interferer are described. The peak-to-average ratio of a received signal is used to determine the type of interferer. The ratio and interferer type, in addition to the type of on-channel signal, are used to select parameters to adjust the decay time of a peak detector (516), and the threshold and hysteresis of a comparator (518). The peak detector (516) and comparator (518) are used to generate an off-channel flag that indicates the presence of a relatively strong interferer to other modules in the receiver (500). If valid data is not present a default set of parameters is provided. The ratio is determined by dividing the maximum peak over the average or a range of ratios is determined by comparing a scaled value of the average to different scaled values of the peak.Type: GrantFiled: September 2, 2011Date of Patent: March 31, 2015Assignee: Motorola Solutions, Inc.Inventors: Moshe Ben Ayun, Ricardo Franco, Ovadia Grossman, Mark Rozental, Uri Vallach

Publication number: 20130315344Abstract: A linear RF transmitter (100) includes a forward path including a baseband signal combiner (109) and an RF (radio frequency) power amplifier (123), and a linearizing control loop from an output (127) of the RF power amplifier to an input of the combiner (109). A feedback control path (105, 107) of the loop delivers a baseband error control signal to the combiner. The transmitter further includes a test signal generator (102) to apply to the combiner in a closed loop level training mode a test signal comprising a voltage Vin which increases with time in a non-linear manner approaching an asymptotic limit such that in response an output signal produced by the combiner is a voltage Ve which is substantially constant over a period of time.Type: ApplicationFiled: September 21, 2010Publication date: November 28, 2013Applicant: MOTOROLA, INC.Inventors: MOSHE BEN-AYUN, OVADIA GROSSMAN, MARK ROZENTAL, URI VALLACH
