Abstract: A receiver circuit for receiving an input signal (IDD, UDD) comprises a detector circuit (111, 111a, 111b, 111c, 111d, 111e, 111f), which is in the form of a sample-and-hold circuit for determining a reference level of the input signal or in the form of a filter circuit for generating a mean value of levels of the input signal (IDD, UDD). The detector circuit generates, on the output side, a referential signal (RS), which is supplied to comparator circuits (113a, 113b, 113c, 113d, 115a, 115b, 115c, 115d). The comparator circuits (113a, 113b, 113c, 113d, 115a, 115b, 115c, 115d) compare an offset level of the input signal (IDD, UDD) with the referential signal (RS) and generate data signals (DATA, DH, DL). The offset input signals (IDD, UDD) are evaluated relatively in respect of the reference level or the mean value of the levels of the input signal.

Abstract: A method is suggested for sensing light being incident on an electronic device. The electronic device comprises a display and a light sensor arrangement mounted behind the display such as to receive incident light through the display. The method comprises periodically switching the display on and off depending on a control signal, wherein a period is defined by a succession of an on-state and an off-state of the display. A sensor signal is generated by integrating the incident light by means of the light sensor arrangement for a total integration time comprising a number of periods. A first signal count is determined from the sensor signal being indicative of an amount of integrated incident light during an on-state. A second signal count is determined from the sensor signal being indicative of an amount of integrated incident light during an off-state. A third signal count is determined from the sensor signal being indicative of an amount of integrated incident light during the total integration time. Finally, an ambient light level is determined depending on the first, second and third signal counts.

Abstract: We disclose herein a method of compressing data for data transfer within an electronic device. The method comprises: receiving, at a first processing member of the electronic device, a plurality of data samples produced by a member of the electronic device, wherein the data samples comprise numerical bits; restructuring, by the first processing member, the plurality of data samples into a plurality of data packets; labelling each data packet with a sample indicator bit to indicate a plurality of groups across the plurality of data packets; transferring a bit stream comprising at least some of the plurality of data packets across an interface of the electronic device to a receiving member of the electronic device; and decoding the bit stream, by a second processing member of the electronic device, to obtain at least some of the plurality of the data samples, the decoding being based at least in part on the sample indicator bits.
