  • Method and circuit for the time-continuous detection of the position of the sensor mass with simultaneous feedback for capacitive sensors
    Patent number: 10139230
    Abstract: The invention relates to a detection circuit for reading out at least one position signal of a micromechanical capacitive sensor having at least one oscillating element that can be excited so as to move in an oscillating manner. In particular, the invention relates to a sensor that is operated in a closed control loop by using the detection circuit according to the invention. The invention further relates to a method for operating such a sensor. During operation, a first input connection of the detection circuit (100) is connected to an output connection of the capacitive sensor (106) and an output connection of the detection circuit (100) is connected to a loop filter of a control loop (102), wherein the control loop feeds back a feedback voltage for providing a restoring force in dependence on an output voltage of the control loop (102) to a second input connection of the detection circuit (100).
