Publication number: 20230044817Abstract: A method of measuring light intensity comprising exposing a photodiode to light to cause the photodiode to provide a current of a first polarity, supplying said current to an integrator to integrate said current to provide an integrated output voltage, and comparing the output voltage with a threshold voltage. Charge packages of opposite polarity are applied to said first polarity to reset the integration voltage prior to the start of the integration time. At the end of the integration time, the photodiode is disconnected from said integrator and a reference voltage coupled to the integrator input, whilst a resistance is coupled into the circuit until the comparison signal switches. The comparison signal is monitored to measure a time between the end of the integration time and the switching of the comparison signal to provide a measure of a residual voltage.Type: ApplicationFiled: December 7, 2020Publication date: February 9, 2023Applicant: ams International AGInventor: Peter BLIEM

Publication number: 20220103165Abstract: An example system includes an input terminal operable to receive an input signal having first pulses, a first delay circuit, a second delay circuit, and a latch circuit. The first delay circuit is operable to generate a first delay signal based on the input signal. The first delay signal has second pulses, each including a respective falling edge that is delayed in time with respect to a corresponding falling edge of the first pulses. The second delay circuit is operable to generate a second delay signal based on the input signal. The second delay signal has third pulses, each including a respective falling edge that is delayed in time with respect to a corresponding rising edge of the first pulses.

Patent number: 11029197Abstract: An optical sensor arrangement has an integrator, a photodiode for providing a current corresponding to a first polarity, a comparator coupled to the integrator for comparing a voltage with a threshold voltage to provide a comparison output, a reference charge circuit and a control unit. The reference charge circuit is coupled to the integrator for selectively providing first charge packages of a first size or second charge packages of a second size. The control unit is configured to control operation in a calibration phase, in an integration phase and in a residual measurement phase. During the calibration phase, the reference charge circuit provides one of the first charge packages and one or more of the second charge packages to the integrator until the comparison output changes. A reference number is determined corresponding to a number of the second charge packages provided.Type: GrantFiled: June 8, 2018Date of Patent: June 8, 2021Assignee: ams AGInventors: Bernhard Greimel-Längauer, Peter Bliem

Patent number: 10950187Abstract: 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.Type: GrantFiled: February 7, 2018Date of Patent: March 16, 2021Assignee: AMS AGInventors: Josef Kriebernegg, Bernhard Greimel-Rechling, Herbert Lenhard, Peter Bliem, Joachim Lechner, Christian Halper, Manuel Hoerbinger

Patent number: 9698679Abstract: A circuit for DC-DC conversion with current limitation comprises a DC-DC converter (100) with a coil (110) and a controllable switch (120) that can be switched into a low-impedance and a high-impedance state, and a current limiter (300a, 300b) for generating a control signal (IOC) for controlling the state of the controllable switch in the DC-DC converter (100). The current limiter (300a, 300b) is constructed such that the current (IL) through the coil at which the current limitation takes place is nearly independent of the ratio of the on-times and off-times of the controllable switch in the DC-DC converter (100).Type: GrantFiled: October 19, 2012Date of Patent: July 4, 2017Assignee: AMS AGInventors: Thomas Jessenig, Manfred Lueger, Christian Halper, Peter Bliem
