  • Patent number: 8089275
    Abstract: A sensor arrangement has a sensor array (SA) with a first, a second, and a third sensor focus (SSP1, SSP2, SSP3), which are located along a main linear direction (L) and in which the third sensor focus (SSP3) is located in the middle between the first and second sensor foci (SSP1, SSP2). Individual sensor devices (SM1, SM2, SM3) with magnetic field sensors that provide a first, second, and third set of sensor signals are correlated with the sensor foci (SSP1, SSP2, SSP3). A first and a second channel signal (CH1, CH2) are derived as a function of the sets of sensor signals in a processing device (PRC) via a first and a second combination device (K1, K2). An evaluation unit (EV) is configured to derive a phase angle as a function of the channel signals (CH1, CH2).

  • Patent number: 6822596
    Abstract: An analog/digital converter includes a first transfer circuit which receives an input voltage and outputs an output clock signal having a phase delay that is dependent on the input voltage, a second transfer circuit which receives a reference voltage and an input clock signal and outputs a reference clock signal having a phase delay that is dependent on the reference voltage, and a comparator which compares the output clock signal and the reference clock signal and outputs a digitally-coded output signal that is based on the result of the phase comparison of the output clock signal and the reference clock signal.
