Patent number: 11971316Abstract: A stress and/or strain measurement cell for a stress and/or strain measurement system. The cell includes a reference contact, a sensor contact and a first current mirror circuit which is integrated into a semiconductor material and has a first conduction path connectable or connected to the reference contact and a second conduction path connectable or connected to the sensor contact. The first conduction path includes a first transistor and the second conduction path includes a second transistor. A first crystal direction of the semiconductor material oriented perpendicular to a first inversion channel of the first transistor is definable for the first inversion channel and a second crystal direction of the semiconductor material oriented perpendicular to a second inversion channel of the second transistor is definable for the second inversion channel. The first crystal direction of the semiconductor material is inclined relative to the second crystal direction of the semiconductor material.Type: GrantFiled: May 26, 2022Date of Patent: April 30, 2024Assignee: ROBERT BOSCH GMBHInventors: Falk Roewer, Clemens Jurgschat, Torsten Ohms

Patent number: 7061230Abstract: A circuit for measuring distances and which has at least two inputs (1, 2), at least one measuring coil (3), and at least one signal source, wherein at least two input signals (epos, eneg) are generated by means of the signal source, and the inputs (1, 2) are activatable by means of the input signals (epos, eneg). The input signals (epos, eneg) are applied, preferably preprocessed, to the inputs of the measuring coil (3). The circuit is designed for use where little space is available for the circuit, with the input signals (epos, eneg) being applied to a preferably timed SC network, which generates a measuring output signal that is dependent on temperature. A corresponding method is also described.Type: GrantFiled: March 18, 2004Date of Patent: June 13, 2006Assignee: Micro-Epsilon Messtechnik GmbH & Co.
