  • Signal processing unit and method for time of flight measurement
    Patent number: 10353058
    Abstract: A signal processing unit for time of flight measurement includes an oscillation module, a transmission module, a detection module, a multiplier, an analog-to-digital-converter and a processing module. The oscillation module provides m reference phases. The transmission module generates a set of light impulses based on a selection phase selected out of the m reference phases. The detection module receives a set of reflections of the set of light impulses and to generate a detector signal based on the set of reflections. The multiplier obtains a result of a multiplication of the detector signal by a comparison phase. The analog-to-digital-converter converts the result of the multiplier into a digital signal. The processing module determines the comparison phase or the selection phase and calculates an approximate phase difference between the set of generated light impulses and the set of received reflections based on the digital signal.

  • Differential driver with common mode voltage tracking and method
    Patent number: 8363705
    Abstract: In a transceiver, a transmitter circuit is provided substantially the same common-mode voltage regardless of whether the transceiver is in a transmitting or receiving mode. In one embodiment, the transmitter circuit includes a driver circuit which, in the transmission mode of the transceiver, drives an output differential signal, and which, in the receiving mode of the transceiver, provides a termination circuit for an input differential signal. A variable resistor is provided to connect between a supply voltage and the driver circuit, the resistance of the variable resistor is selected such that the common-mode voltage of the output differential signal of the transmission mode substantially equals the common-mode voltage in the input differential signal of the receiving mode.
