  • Precision current reference generator circuit
    Patent number: 9785178
    Abstract: A current reference generator includes a first voltage reference configured to generate a first current through a first resistor; a second voltage reference configured to generate a second current; a first current mirror configured to subtract the second current from the first current to generate a temperature invariant current; a third voltage reference configured to generate a third current via a second resistor; and a second current mirror configured to: subtract the temperature invariant current from the third current to produce a process-temperature invariant current, and output the process-temperature invariant current.
    Type: Grant
    Filed: March 17, 2016
    Date of Patent: October 10, 2017
    Assignee: KING ABDULAZIZ CITY FOR SCIENCE AND TECHNOLOGY

  • READOUT-INTERFACE CIRCUIT FOR A CAPACITIVE MICROELECTROMECHANICAL SENSOR, AND CORRESPONDING SENSOR
    Publication number: 20090322353
    Abstract: In a capacitive sensor, a detection structure, of a microelectromechanical type, is provided with a fixed element and a mobile element, capacitively coupled to one another, generating a capacitive variation as a function of a quantity to be detected, and with a parasitic coupling element, capacitively coupled to at least one between the mobile element and the fixed element generating a first parasitic capacitance, intrinsic to the detection structure; a readout-interface circuit is connected to the detection structure and generates, on an output terminal thereof, an output signal as a function of the capacitive variation. The readout-interface circuit has a feedback path between the output terminal and the parasitic coupling element so as to drive the first intrinsic parasitic capacitance with the output signal.
