  • True random number generation in systems on chip
    Patent number: 9747078
    Abstract: A device for true random number generation is disclosed. The device comprises an antenna and an analog processing unit for analog processing of a signal received from the antenna. An analog to digital (AD) converter is used for converting an analog signal generated by the analog processing unit into a digital signal. An isolation means is applied for temporarily isolating the antenna from the analog processing unit and the AD converter to generate a noise signal. A sampling means is used for sampling output values generated by the AD converter when the antenna is isolated from the analog processing unit and the AD converter. A digital processing unit is used for processing the sampled output values generated by the AD converter. The digital processing unit is configured to generate a random number based on one or more of the output values generated by the AD converter.

  • DC blocker for a high gain complex circuit
    Patent number: 9083281
    Abstract: An amplifying circuit comprises an analog amplifying circuit having an analog input for receiving an analog input signal to be amplified and an analog output for outputting an amplified analog signal, wherein the amplifying circuit comprises an implementation of a complex transfer function. A feedback circuit has a feedback circuit input and a feedback circuit output, wherein the feedback circuit comprises an implementation of an inverse transfer function that is an estimation of an inverse of at least a DC component of the complex transfer function of the analog amplifying circuit. The feedback circuit input is arranged for receiving a signal that is based on the amplified analog signal of the analog amplifying circuit. The analog circuit is arranged for receiving a bias signal that is based on the feedback circuit output.
