Patent ID: 11971316
Assignee: ROBERT BOSCH GMBH
Field: Measurement (Instruments)
Classification: CPC G  H | IPC G  H

Claim 1:
2. The stress and/or strain measurement cell as recited in claim 1, further comprising:
a second current mirror circuit integrated into the semiconductor material with a third conduction path connectable or connected to the reference contact or to a further reference contact and with a fourth conduction path connectable or connected to the sensor contact or to a further sensor contact, the third conduction path of the second current mirror circuit including at least one fifth transistor, and the fourth conduction path of the second current mirror circuit including at least one sixth transistor;
wherein a fifth gate terminal of the fifth transistor, a fifth drain terminal of the fifth transistor and a sixth gate terminal of the sixth transistor are at an identical potential;
wherein a fifth crystal direction of the semiconductor material oriented perpendicular to a fifth inversion channel of the fifth transistor is definable for the fifth inversion channel, and a sixth crystal direction of the semiconductor material oriented perpendicular to a sixth inversion channel of the sixth transistor is definable for the sixth inversion channel, the fifth crystal direction of the semiconductor material being inclined relative to the sixth crystal direction of the semiconductor material, and
wherein the fifth crystal direction of the semiconductor material is inclined relative to the first crystal direction of the semiconductor material and/or the sixth crystal direction of the semiconductor material is inclined relative to the second crystal direction of the semiconductor material.
