  • Publication number: 20200212927
    Abstract: An acquisition stage receives a digital input signal and generates therefrom a first digital signal and a second digital signal complementary thereto. First and second processing stages receive the first and second digital signals and generate therefrom first and second analog signals in time with first and second complementary clock signals. An output stage generates an internal clock signal equivalent to one of: the first clock signal phase shifted by a duration of a transient occurring during a period of the first clock signal, or the second clock signal phase shifted by a duration of a transient occurring during a period of the second clock signal. The output stage produces an analog output signal equal to the first analog signal when the internal clock signal is at a first logic level, and equal to the second analog signal when the internal clock signal is at a second logic level.

  • Patent number: 10634705
    Abstract: A first resistor and a second resistor are coupled in series between a voltage source and an active load. When the current drawn by the active load exceeds a current threshold corresponding to a maximum admissible voltage drop across the first resistor, a stabilization current is delivered to the node common to the series coupled first and second resistors in such a way as to stabilize the voltage on the terminals of the active load at a threshold value. In the presence of such a current in excess of the current threshold, the current consumed by the active load is measured from the voltage drop across the second resistor. Conversely, if the current is less than the current threshold, the current consumed by the active load is measured from the voltage drop across the first resistor.

  • Patent number: 10560020
    Abstract: A method can be used for compensating a voltage drop on a cable connected between a source device and a receiver device. The source device delivers an offset current on a channel configuration pin of the source device, the offset current causing an increase in a voltage on the channel configuration pin of the source device to a chosen reference voltage. The offset current is stored in the source device. The source device absorbs an absorption current originating from the channel configuration pin of the source device, the absorption current depending on the stored offset current and on the voltage drop. The source device generates a compensated supply voltage on a power supply pin of the source device, the compensated supply voltage equal to a reference supply voltage increased by the voltage drop to within a tolerance.
