Patent number: 9774299Abstract: An embodiment of an amplifier system includes a modifiable signal adjustment device with an RF signal adjustment circuit coupled between first and second nodes. The RF signal adjustment circuit includes an adjustable phase shifter and an adjustable attenuator coupled in series with each other. The device also includes a memory and a controller circuit. The controller circuit retrieves a phase shift value and an attenuation value from the memory. The controller circuit then controls the adjustable phase shifter to apply a phase shift corresponding to the phase shift value to an input RF signal received at the first node, and controls the adjustable attenuator to apply an attenuation corresponding to the attenuation value to the input RF signal. Applying the phase shift and the attenuation results in an output RF signal at the second node.Type: GrantFiled: September 29, 2014Date of Patent: September 26, 2017Assignee: NXP USA, INC.Inventors: Joseph Staudinger, Abdulrhman M. S. Ahmed, Paul R. Hart, Monte G. Miller, Nicholas J. Spence

Patent number: 9772963Abstract: An interrupt management system for managing multiple interrupts includes a timer and an interrupt management sub-system. The interrupt management sub-system receives first and second interrupts, determines the first interrupt to be a real-time interrupt and the second interrupt to be a non-real-time interrupt, initializes the timer for a predetermined time period on reception of the first interrupt, and determines whether the second interrupt is either a maskable or non-maskable interrupt. The interrupt management sub-system transmits the first interrupt to an interrupt controller, en-queues the second interrupt during the predetermined time period, and transmits the second interrupt to the interrupt controller after the predetermined time period when the second interrupt is a maskable interrupt. The interrupt management sub-system transmits the second interrupt to the interrupt controller during the predetermined time period when the second interrupt is a non-maskable interrupt.Type: GrantFiled: July 26, 2015Date of Patent: September 26, 2017Assignee: NXP USA, INC.Inventors: Priyanka Jain, Girraj K.

Patent number: 9766289Abstract: An integrated circuit (IC) includes a logic built-in self-test (LBIST) system that includes scan chains. The scan chains receive a clock signal and test pattern signals, and generate scan out signals. A debug controller receives the scan out signals and shifts a set of the scan out signals to a joint test action group (JTAG) controller. The debug controller also maintains a dynamic count indicative of the number of debug shift operations performed, and compares the dynamic count with a final count. If the dynamic count is less than the final count, the debug controller performs a second debug shift operation, which facilitates determination of a fault location in the IC.Type: GrantFiled: October 6, 2015Date of Patent: September 19, 2017Assignee: NXP USA, INC.Inventors: Mayank Parasrampuria, Anurag Jindal, Sagar Kataria
