Patent number: 11081973Abstract: An inverter is presented. The inverter may be configured to receive an input voltage at an input node of the inverter, and to generate an output voltage at an output node of the inverter. The inverter may comprise a first transistor coupled between a supply node and the output node of the inverter. Further, the inverter may comprise a second transistor coupled between the output node of the inverter and a reference node. The input node of the inverter may be coupled to a back-gate of the first transistor and to a back-gate of the second transistor.Type: GrantFiled: October 30, 2019Date of Patent: August 3, 2021Assignee: Dialog Semiconductor B.V.Inventors: Marinus Wilhelmus Kruiskamp, Petrus Hendrikus Seesink

Patent number: 10847189Abstract: A voltage regulator and a method for generating a retention voltage for a RAM cell that is sufficiently high to prevent data loss, while minimizing leakage currents are presented. The A voltage regulator is used for generating at least one voltage. The regulator contains mirror circuitry, a leakage device coupled to the mirror circuitry, and a first resistive device coupled to the mirror circuitry via a first output node. The mirror circuitry mirrors a leakage current from the leakage device to the first resistive device, and the leakage current contributes to the generation of a first reference voltage at the first output node.Type: GrantFiled: August 21, 2018Date of Patent: November 24, 2020Assignee: Dialog Semiconductor B.V.Inventor: Petrus Hendrikus Seesink

Patent number: 10554218Abstract: A sigma-delta modulator and method for converting an input voltage such as an analog signal into a digital signal is presented. The modulator may be used as an analog-to-digital converter (ADC). The modulator has a plurality of bias transistors with at least one p-type transistor and at least one n-type transistor. The modulator receives a bias voltage, wherein each bias transistor receives the same bias voltage. This sigma-delta modulator results in reduced power consumption.Type: GrantFiled: November 21, 2018Date of Patent: February 4, 2020Assignee: Dialog Semiconductor B.V.Inventor: Petrus Hendrikus Seesink

Patent number: 10459470Abstract: A digital voltage regulator and a method to regulate an output voltage at an output node based on an input voltage is presented. The regulator has a driver stage with N driver slices, with N>1. Each of the N driver slices can be activated or deactivated individually. A driver slice comprises a current source to provide an output current component to the output node, if the driver slice is activated. Furthermore, the regulator has a control unit to activate a number n of the N driver slices, based on a deviation of a feedback voltage from a reference voltage, where the feedback voltage is dependent on the output voltage.Type: GrantFiled: May 11, 2018Date of Patent: October 29, 2019Assignee: Dialog Semiconductor (UK) LimitedInventors: Mihail Jefremow, Dan Ciomaga, Gennadii Tatarchenkov, Stephan Drebinger, Fabio Rigoni, Alessandro Angeli, Petrus Hendrikus Seesink

Publication number: 20190296727Abstract: A digital active diode circuit for letting current pass in one direction and substantially blocking current in the opposite direction is presented. The circuit contains switching means comprising an array of switches, a first comparison unit coupled to the digital active diode circuit input and output. The first comparison unit updates its output if the difference between their inputs is higher than a first threshold voltage, and a second comparison unit being coupled to the digital active diode circuit output and input. The second comparison unit updates its output if the difference between its inputs is lower than a second threshold voltage. The switching means switches on or off at least one switch based on the comparisons performed by the first comparison unit and the second comparison unit and wherein the first threshold voltage is different from the second threshold voltage.Type: ApplicationFiled: March 23, 2018Publication date: September 26, 2019Inventors: Marinus Wilhelmus Kruiskamp, Petrus Hendrikus Seesink
