  • Patent number: 9401728
    Abstract: The test signal generator generates an analog and digital test signals to test a sigma-delta ADC which has an analog portion succeeded by a digital decimation filter. The test signal generator supplies a first digital test signal having a first particular number of bits N and a first particular bit rate RN corresponding to digital signals occurring after the digital decimation filter. A digital sigma-delta modulator converts the first digital test signal into a second digital test signal having a second particular number of bits M<N thereby corresponding to a digital signal occurring at an input of the digital decimation filter. A DAC converts the second digital test signal into an analog signal, and a filter to filter the analog signal to obtain an analog test signal for testing the analog portion.

  • Patent number: 9401723
    Abstract: An XOR phase detector for a phase-locked loop PLL comprises an XOR gate which has an input for a periodic reference signal and another input connected to a frequency divider of the PLL. A level shifter has a level shifter input connected to an output of the XOR gate and a level shifter output connectable to a voltage-controlled oscillator VCO of the PLL. The level shifter is connectable between low and high voltage providers and has a high level and a low level. The level shifter is arranged to deliver at its output the high level or the low level depending on whether the voltage at the output of the XOR phase detector is low or high. The level shifter further has a setpoint input for setting the high level to a setpoint level.

  • Patent number: 9400861
    Abstract: There is described a method of optimizing the design of an electronic device with respect to electromagnetic emissions based on frequency spreading. With the method, a designer can, for example, perform a transient simulation on the device only once, and then add frequency spreading with specific parameters by simulation. The resulting frequency spread signal can be observed. The designer can thus evaluate the reduction in electromagnetic emission level, and repeat this process by iteratively applying frequency spreading each time with specific parameters but without having to modify the schematic of the device and to perform another simulation of the device. The method according to this innovation is extremely rapid as the simulation of the design does not need to be repeated at each run of the frequency spreading simulation.

  • Publication number: 20160210260
    Abstract: A resource domain controller in a data processing system stores information that is used to group various resources, such as bus masters and peripherals, into common domains. Each group can be referred to as a resource domain and can include one or more data processor and peripheral devices. The resource domain information is then used to determine whether a particular access request from a data processor is authorized to access its intended target, e.g., one of the peripheral devices, by determining whether the access request and the intended target each belong to a common resource domain. If so, the access request is allowed, otherwise the access request is prevented from being successfully completed.

  • Publication number: 20160212644
    Abstract: There is provided a method of estimating a bit error rate in a transport channel of a wireless communication system. The method comprises the receiving a signal from a remote transmitter of the wireless communication system via a physical channel, the signal comprising data and noise forming a plurality of soft bits. The method further comprises the counting, during a period of time, a number of erroneous bits being those soft bits which have an amplitude below ?2A or above +2A with A being the average amplitude of the soft bits received. Next, the number of erroneous bits is divided by a number of total bits received during said period of time in order to obtain the bit error rate. This method provides a way to estimate the BER value without knowing the exact shape of the noise distribution. In an embodiment a selection is made between two estimation algorithms.
