Movement correction data for each echo train is updated at the start of the echo train and is then updated again at most partially for the spin echoes.
Abstract: The present invention relates to a circuit arrangement and a method for reading a capacitive vibratory gyroscope with an at least primary mass and at least one secondary mass that is connected to the primary mass, wherein the primary mass is excited to a primary vibration during operation, and wherein the secondary mass is deflected out of a resting position in a direction that is transversal to the primary vibration when the vibratory gyro-scope rotates around a sensitive axis.
Abstract: A charge balancing circuit is adapted to be connected to an electrode and to a stimulation source. The charge balancing circuit has an electrode terminal for receiving an electrode voltage, an amplifier coupled to the electrode terminal and adapted to amplify and invert the electrode voltage for generating an intermediate voltage and a compensation stage. The compensation stage is adapted to generate an output current if the electrode voltage lies outside a specified safety range and to generate the output current depending on the intermediate voltage. The compensation stage is further adapted to supply the output current to the electrode terminal for driving the electrode voltage towards and/or into the safety range.
