  • Patent number: 9515642
    Abstract: In a device, a pulse modulation switching logic is provided to generate switching signals of a pulse modulator so as to generate a pulse modulated signal with a first pulse modulation control parameter and a second pulse modulation control parameter. The first pulse modulation control parameter is controlled on the basis of a first control signal, and the second pulse modulation control parameter is controlled on the basis of a second control signal. A first control loop is provided to generate the first control signal from an output signal derived from the pulse modulated signal. A second control loop is provided to generate the second control signal on the basis of the output signal. The first and second control signals are applied to concurrently control the first and second pulse modulation control parameters.

  • Patent number: 9503121
    Abstract: A modulator is configured to respond to input swings by providing a feedback voltage via a feedback path to compromise an increase in noise and distortion power with increasing signal power at signal levels exceeding a predetermined threshold. A digital-to-analog converter (DAC) generates a feedback voltage with a resistor string biased with a given current and switches as a function of an input value to mitigate the voltage swing at a summing node.

  • Publication number: 20160291935
    Abstract: A pseudorandom binary sequence having a first sampling rate is generated. Based on the pseudorandom binary sequence, a digital filter generates a spectrally shaped pseudorandom binary sequence having a second sampling rate. The second sampling rate is equal to the first sampling rate multiplied by an integer upsampling factor of L>1. The digital filter includes L filter branches consisting of a first subset of one or more filter branches and a second subset of one or more filter branches. Each filter branch of the first subset generates a binary output which is equal to an input of the filter branch. Each filter branch of the second subset generates a binary output which is inverted with respect to an input of the filter branch.

  • Patent number: 9425757
    Abstract: A controller for controlling an amplification gain of an amplifier for amplifying a high dynamic range signal for an analog to digital converter comprises an input interface adapted to receive a representation of the high dynamic range signal and a signal compressor adapted to provide a low amplitude representation of the high dynamic range signal, the low amplitude representation having a lower signal amplitude than the high dynamic range signal. A comparator is adapted to compare the signal amplitude of the low amplitude representation with a predetermined threshold and an output interface is adapted to provide a control signal to the amplifier, the control signal being adapted to control the amplification gain of the amplifier such that the amplification gain is lowered when the signal amplitude of the low amplitude representation exceeds the predetermined threshold.

  • Patent number: 9071263
    Abstract: Representative implementations of devices and techniques provide analog to digital conversion of analog inputs. A plurality of analog-to-digital converters (ADCs) can be arranged such that one or more of the ADCs is operating at a sampling rate that is less than others of the plurality of ADCs. For example, a sampling rate interpolator may be used to increase a sampling rate of signals output at the one or more ADCs operating at the lower sampling rate, allowing pipelining of the plurality of ADCs.

  • Publication number: 20140266260
    Abstract: An apparatus for generating a sensor signal indicating information on a capacitance of a variable capacitor including a variable capacitance includes a sensor unit and a compensation unit. The sensor unit is configured to generate a sensor signal indicating information on a varying current flowing through a connection between the sensor unit and the variable capacitor caused by a variation of the capacitance of the variable capacitor while the variable capacitor is biased by a predefined bias voltage. Further, the compensation unit is configured to influence the sensor signal or to provide a compensation signal capable of influencing the sensor signal so that the sensor signal includes less nonlinear signal portions than a sensor signal without the influence of the compensation unit or the compensation signal.
